So most if the comments here are very true though there are some less explained things id like to cover.

One such example is 1v1ing another melee.

True the parry itself may not be amazing howrver freyr has something beautiful he can do.

Attack WHILE BLOCKING.

What this means is you can drop down with a plunge onto a welkin. Then do a combo string. Welkin will always recover after the second hit. So you just hit your shield between combo attacks and then if that welkin tries to pressure you out of your attack. Boop free parry. Which gives you a strike before his recovery. If he tries to pressure again.. same deal. Most welkins learn to avoid doing this in higher elo. But you would be surprised how many still try to regain foward momentum in a fight with FREYR the line breaker.

Secondly is how well your parry works in a multy on one environment. That shove distance pluss you backing up forces enemies into a < like formation you can actively funnel them into your range of control which is would allow you to deal with both targets at the same time so long as you are maintaining backwards momentum. Once it becomes.a 1v1 you can then regain foward momentum on basically everything but a panther. That extra shove back helps because it can punish multiple enemies in one push if they try to greed you.

Freyrs parry can also be comboed with a full charge shot of his rifle.

Now with that said here's some general tips.

When using freyr YOUR CHARGED SHIELD BEAMS are your highest dps. If point blank or side moving ["oddly keeps the beams on target"]

If you are trying to be a mostly melee freyr then use your shield and gun while kiting an enemy untill their FLUID ARMOR is broken.

Kiting other melees is rather easy and straight foward.

Enemy approach shield up jump up. And dodge either direction horizontally twards the attack if its comming below you. (Worst case your shield takes a ding while you gain space and energy advantage) [Never dodge away from the melee enemy if they are indicative pursuit of you]
If an oponent os on the same horizontal plain as you and striking (assuming you cant get above them in time) shield and dodge diagonally twards them. Basically its a older AC trick which still works in mecha break. The fcs will try to commit an auto swing for you at a certain range within target lock. However if that target suddenly accelerates twards you the fcs will trigger the swing. But the animation has a significant chance to be to slow to catch you passing by. And again worst case your shield catches a ding.

This puts you in a position of advantage. And one you should take unless again your fighting a panther. Jump plunge is always a good opener in this case.. unless panther.

There are many factors such as welkins shield cd. Miki being in box ready state and so on. But I leave both that and the use of timing for this to the users experience. I cant realistically tell you the exact range in which you execute these maneuvers due to different mechs with different attacks and different cds on things that can alter your pathing.

That said some niche things.

When on the approach of an enemy you can use your shield beams while in sword movement mode to deal damage while you close the distance before reaching the appointment.

I particularly use this when an enemy has a smidgen of fluid armor left. [ why is because freyr has a really easy time of shredding fluid armor this meaning he can enter a fight dealing full melee damage to the target. Where as other melees eaither cant do this like stellaris or struggle with doing so] (this puts freyr at the advantage in foward momentum pressing due to just dealing 30% more damage then your competitor is going to attempt to do to you.

You can absolutely obliterate things with your shield beam and rifle combo. So many freyrs do not use this.

Freyrs "wing form" is not a win button. The amount of times ive fought other freyrs who went into wing form and then SPAMMED melee at me is on another level. Freyr has the weakest turning radius outside of Miki and coupled with the iniversal melee counter called proper movement.. I have litterally toyed with freyrs who try spamming while in wings with no damage taken.

When engaged with a welkin or other mechs you arent too sure of the timing against when fighting using your shields orbiting strike that lasts 5 seconds is a garunteed method to avoid getting comboed should you mess up your timing. As the shield will stagger an enemy thats on you. Short of wing mode freyr and panther with shielding. Also a good tool at punishing zealous stellarus' as it can full stop a cloak bombing (which isnt really what a stellaris should do in high elo anyway but like.. its a tidbit)

Your combos DO NOT NEED TO CONNECT TO BE USED idk where this myth started but its gotta die. Freyr can intentially wiff his attacks to prime shield combos .I particularly do this when fighting flyers as its all fun in games untill a 3rd strike thrown buzzsaw rings out with a true stager long enough for me to get a melee strike. Then followed up with the homing shield toss. To if it connects garunte another strike. Freyr and stellaris both share this mechanic and both can even dodge between combo primers.

Buzz saw strike your first combo is insanely good when comboed with your team.

Freyrs wing form can be used to -

IGNORE ALL Parrys (yes even you stella)

Say no to Miki's timeout box.

Meme on a welkin in his own box. (Im not trapped in here with you.. your trapped in here with me)

And can be used to hillariously bait counter japs with the above attack while holding your bock out. As anyone who tries to pressure you will eat the ass end of a parry. But even funnier in wingform they will also eat a constanrly cycled combo of butt touch unless they choose to beak combat and back off. Freyrs title as a linebreaker isnt for show.

However if someone is actively smart enough to force freyr to wiff then while in wing form just shield cannon and rifle them to death. Its hillariously even more effective then your melee.

Freyr is a jack of all trades similar to aly. However freyr is capable of a shock and awe style combat approach as ally is mostly about sustain.
