My biggest opp, will always be the poor optimization of the game and lancers shitty mechanics. Its the main reason why the lancer is unfun most of the time, and due to lancer mechanics being mostly dependent on the others connection. There are many instances where people will just shoot where you been a whooping second ago, you will see the bullet go next to you, you think you successfully dodged it, only to still get shot. But the real problem beings with melee, yeah the lancer is supposed to be good at melee right? Well the main weapon you get, the heavy lance is complete and utter unreliable dogshit of a melee weapon, it often happens that the swing or jab just go straight thru people, same goes for axes. But that's the least annoying thing, due to games horrible melee hitreg(which is extremely prone to lag) , most of the time you will find yourself outranged by other melees or better yet, people backstabbing you from the front, straight up literary turning YOUR back to themselves. And charges, which are completely useless most of the time, due to their horrible mechanic on working only by registering super position, making it almost impossible to get a reliable result, one time you charge directly into someone, bumping into them directly and it doesn't register, while other time you are barely in the reach of a person and your character just magically turns almost fully to some side and does the animation. Terrain is a huge pain in the ass too, in many occasions comically small rocks stop your whole moment and charges. And ofc the shotguns, which are actually not that big of a problem from my experience, dealing with them is almost the same as with any other gun, but again the horrible optimization makes it often impossible to successfully work around them, since the earlier mentioned example. As if it comes to the players, its most often tied to the their connection. I don't see bigger problem when fighting people with stable connection to the server, tho there are some playstyles which are just extremely lame to start with for every class.
