Are you forgetting that as a Titan, you can use the shield to bounce off enemies ( or PVP ) in a tracking formation, Then go charging like a tank into enemies voiding them out of existence... or not use the shield but instead leap in the air ( hold down R1+L1 ) and you get to use the Ward of Dawn Titan bubble? Or with Warlock - Void. You can Overcharge your grenade by taking some juice out of super ( doesn't have to be fully charged ) and deal much more damage? There are some new mechanics like these and obviously when they show us how to mods we Can flip things around. There are 14 mod slots in armor and weapons. So it's possible the cooldowns for the abilities will be ready at launch. Till then. You can always jump in the air as a dawnblade warlock, make some kills and lessen the cooldown for your melee and grenades. Haven't played much as arcstrider/hunter but I'm sure there are new abilities. They even grey'd out some in the guardian trees if you noticed.
