When playing against players in 1v1 or 2v2 situations with Cole I always throw a crap load of grenades at them if they try and distance themselves or if they have me beat at the close range game like when I'm playing Raiden(specifically Cowjedi's Raiden. He has me beat 2 wins to his 4 lol he's sick). Doing this gets me some fast level 1s and keeps pressure on the player to try and get close again but I constantly hear people whining about it in game. I feel like its a great tool when used in excess. It's not like if your good that alone will lose the game for you.
(Joking, of course. But I don't think they should grant that much AP.)
WHAT IS THIS!?
But do you understand that even if they use it it will not win the game for them. It will take them forever to get to their level 2 and especially 3 with that alone(Good Cole). Just don't get hit by his level one. Chances are people that only spam it are not that great.
If people lose to one move, it's not the one winning that has a skill problem.
You've never seen the infinite Mic Run that PaRappa can do on Sly, then...
In that case it's not a lack of skill, but maybe a lack of scruples.
That being said, Strife may be right, 20 AP may be a bit high for such a ridiculously good move.
