I'm sure the suggestion's been made already but I thought I'd post it anyway. I think there needs to be a bit more control for the special attacks, especially the warlock's absorption ability. This isn't the super we're talking about, but the actual special ability keyed to the melee button. I don't know if I'm alone on this, but it was a little frustrating that the thing would just use it regardless of whether or not you'd already thrown a grenade. It wasn't so much of a problem with the hunter because you had to be at range in order for it to throw a knife, but I still kind of think it should be a separate button. Like, maybe R3 or something. I never got my Titan to a high enough level to use its special so IDK if there's a similar situation there, but I definitely think that the specials should be their own control.
