Nice games guys, as promised, I'll give ya some tips.
Lost: Three things. Like I mentioned in chat, your movement is too straight, you need to move more zig-zaggy and in shorter bursts so you don't lose as much boost quickly and it'll make you a harder target to land hits on.
2nd is that you should cancel a move out if it doesn't look like you'll land it. There were a few times where you shot the Mega Cannon from TGIII and missed but didn't BD out of it for whatever reason. If you run out of boost, then nothing you can do but if you still had some, then you should cancel it as soon as you know it won't hit. You can help that by doing the move without the camera cut, hold down 2 (or back) while doing the attack and TGIII will do it without the camera switching angles.
3rd is that you should get the timing down on landing BR/Main x3. This is the bread and butter damage source in the game and it's not hard per se, just gotta train yourself to do it before you think about it. There were a few times you got me with one or two but if you had repeated it as soon as it hit, you'd have more damage going on.
Pak32; Your running out of boost too much and you're turning and firing your BR which stops you in place and drains your boost as well. Make sure to pay attention to your positioning, not just relative to the enemy but your unit's direction and of course how much boost you're using. Good use of the stun to block melee a few times but be careful because, as I said, the super armor will only take you so far and it doesn't do any actual damage. Your funnel work is pretty good though.
Amish: When playing Cherudim, running away is your biggest priority and you should always try to maintain your distance so the enemy can't melee you. If you're playing with someone you trust and are good, you can be inside bait for your partner to get melee and cuts but if they aren't doing that, then stay away when fighting them. Staying close to them is important as well for protection.
SDN; Don't know if you're reading this but for IJ, using your boomerang and BR is a really good way of getting close to your opponent. Your usage of the boomerang is fine and if you manage to land it on an enemy, going in for the melee might not be a bad idea, assuming the boomer hits. If you're expecting to land melee, you'll also need to be closer in general. You can play IJ from a bit away but you lose a little bit of punch because of the distance/shielding/wathever. You should also use your CSa a bit more so particularly when trying to land hits on enemies that are touching down the ground.
