Ideally we want to be maximizing our dps whenever we raid, not only because we want the contribution bonus and an extra ball, but who really plays to be dead weight?
In most cases max dps comes from our 100 energy moves (full bar), and as far as dps goes charge move > quick move.
Now given the amount of damage that these raid bosses deal, and that dmg taken also charges our energy bar, I find that in some cases I can use an 80 energy (2 bar) or 65 energy (3 bar) almost exclusively and rarely have to use my quick attack.
Now the problem here is that this is very difficult to observe because we don't have combat logs to know how much damage we are actually doing.
What do you think? Do you think you could maximize raid dps/damage by taking more of the 2 bar/ 3 bar charge abilities?
Personally I'm finding that I contribute more with those, as there are times when a pokemon will die (sorry feint) before a single charge move is available (100 energy max dps 1 bar).
