Thanks for the somewhat positive feedback!
I am 90% sure that weapons, you assumed don't work, are the weapons which need chaining. Essentially, the idea is that you have to activate it again after a short time (indicated by yellow marker under the health bar). But we haven't done any tutorial for it, and it is very hard, so I am not surprised it happened.
Loadouts have different intents behind them:
Main, Heero is your regular jack of all trades.
5 meant to be trap/intercept but it didn't really work out, so I will rework it completely
4 is block, counter and general defense. Assuming you haven't figured chaining out, it probably didn't work for you at all
3 is purely random, but right now "random" is limited to 3 basic skills, so it is not very exciting
2 should be good. It is summoner, and it works as intended (as far as I know). But this loadout is much better late game
1 is about status effects. Probably only build which can win a game, because of some interesting combos
Rys is high skill character, so it is not surprising that teleport matrices aren't the easiest thing to use.
The movement and overall speed will be increased. Also, I think the fact that game has almost no healing didn't help
