If there's one complaint I see all over the place, it's that raids don't drop enough loot, and I experience that too; often times I only get 1 item from a full 10/10 CN clear, maybe two if I'm lucky, and most of the time it's things I don't need that just end up getting vendored/traded to other people. The last time I did a Heroic clear, I ended up getting some leggings that I already have, and the token for an offhand...when I've already got a 213 2hander. So effectively nothing.
But then I look at PvP and as far as I can tell, you just do the PvP activities, get points, and then buy the exact gear you want from the vendor. No loot drama, no RNG, no bullshit.
Why can't PvE work like that? Just have bosses drop badges/points that we use to buy gear from vendors. No more getting pissed off at not having the right item drop, no more having 5 people whisper you "need that? need that? need that?" every time you get loot, no more getting things with the wrong stats, etc. You can funnel your points towards the items you want, instead of being at the mercy of loot RNG.
