Shoulder charges are great if you can run unseen but mostly you get shot before you get to your target. All you have to do to beat fist of havoc is to jump up, jump back or walk up a couple of steps. The grenade is next to useless unless some nutter walks into the big bolts of lightning in front of them. All classes have their benefits and weaknesses, if I look at the winner at the end of most pvp matches I usually see a hunter not a titan. Maybe they should have a crucible setting with no abilities and everyone has the same guns then no one can moan......imo it will be a pretty bland though.
