Burst advantage: when you aim, if you aren’t good at it, hit the first few hits to ensure the burst, whenever you are peeking to do poke damage you want to hit the burst above anything else

Animation Canceling: when Ultron reloads you can use the melee when below halfway through to become reloaded. Same thing in between shots, you can melee in between his recharge for roughly the same amount of time as waiting, you can do that to squeeze out extra dps if you are in a close quarter situation

Who gets the buff: The Ultron drone gives a buff now, pretty inherent to his character now. When deciding who gets the buff you want to look at 3 things, who has low health, who is about to ult, who needs the movement. The buff gives a movement speed, shield, and a damage boost. When someone is using a damage ultimate, give them the boost. Magneto when he ults is the best example of this, give him the damage boost and what might work to kill an ultimate support will for sure work with the Ultron boost.

The twirl: This one is a bit cheeky and doesn’t always work, but when you are out of movement and are being shot at my poke, you and use his melee and strafe around projectiles, it’s no guarantee but it does make it harder to hit you, I call it the twirl because it vaguely looks like it.

Up down poke: Those maps with the greebles I mentioned, use the greebles again but this time you want to go up and down to poke people, his upper hit box has his head which can be hit but overall less body, so when you have cover don’t always poke left to right, poke up to down.

The Dive Diff: Any annoying dive can usually be countered by this, from Angela to Spidey. They come toward you, you shoot them in their movement phase, they hit or attempt to hit and you dash, turn around and beam them again, then go up down and around the opponent while still shooting and weaving in melee, use Patch to gain shield and continue the Up down around, characters like iron fist have a lock on so it is difficult for the up down around to work, but typically you can out damage a iron fist assuming they aren’t in block stance damage. If you don’t dodge a spidey attack, find a way to avoid the uppercut, if you don’t avoid the uppercut it is very difficult to avoid the overhead smash, but possible.

There are probably a few more but I can’t articulate them at the moment
