I definitely think there should be a line between pvp and pve in D2. Abilities are all pretty underwhelming in pve, especially when they take like a minute to come back and the striker titan is the only one that gets an extra grenade. I think if nothing else that as the Hunter's dodge class ability is solely for personal use and serves no team advantage it could use a shorter cool down (so could the rest of the abilities tbh). I think either the damage of abilities needs to go up, or the cool downs need to be reduced so that we can have more of them more often. I love the weapon system for D2 although I think we could do with some extremely high impact scout rifles that are very nearly snipers, something that can one shot headshot a cabal but take two or so kill in pvp. And possibly a very close quarters primary like a sawn off shotgun or even a double barrelled hand cannon that has nearly no range but can kill a bigger enemy in one shot at the same time it could have no reload speed making it less desirable for pvp. Either that or we get a lot more power ammo in pve, to make things flow a bit better.
