Personally, I'm super excited for it, even as a primarily PvE player. In D1 I always feel like my heavy weapon is going to waste. I don't need or want a rocket launcher or LMG against most enemies, so they only get any use on bosses. I've always wished I could put a sniper in my heavy slot, because then I'd actually use all those purple ammo boxes that drop before a boss. And most goes d snipers have high enough damage they're still useful against bosses. Putting energy primaries in the second slot sounds like a great move too. I've always thought a Scout Rifle would complement the range of my go-to hand cannons perfectly. I feel like people are worried that if they have to choose between a sniper and a rocket launcher their DPS against bosses will suffer too much. And in D1, they would be right. But don't forget, D2 PvE content will be designed and balanced with the new weapon loadout system in mind. You're not going to be left high and dry with two primaries and a special, because that's what will be expected in D2. I also wouldn't be surprised if snipers, shotguns, and fusions get buffed in D2 to put them more on par with rocket and grenade launchers. Shotguns probably won't need to have their damage drop off a cliff beyond melee range, fusions might be able to fire faster, snipers might be able to be more stable. And all three will likely get much more ammo per drop than grenade and rocket launchers.
