The last thing is a strange idea I've been having for a while. The most problematic gear from Arena/PvP is the weapons, since most of them have their stats better allocated than their PvE counterparts. What's worst is the lack of variety in PvE weapons, forcing some to spec out of their beloved specs because there isn't one at their current raiding level.
Although Blizzard stole some of the thunder (via weapons available now via BoJ), I was thinking of some kind of quest like T0.5 (bear with me, I ding 60 a week after BC). The players would gather items from the raid instance to be handed to the associated faction. After a number of items are handed, the player would receive a weapon that doesn't drop from the instance (for example, off-hand swords for TK).
It is an interesting idea, but I think it’s a bit of a Band-Aid fix that doesn’t address the real underlying problem. The bigger problem is that rogues, warriors, feral druids and healing paladins are too specialized when it comes to weapon types.
This doesn’t really matter in PvP, because you get to choose your weapon type, but in PvE you have to rely on drops from bosses. (You could completely change how PvE loot is distributed, but that is beyond the scope of this post.)
Rogues have it worse off. There are four main weapons for rogues: Daggers, Swords, Fists, and Maces. Each of these types works best when you are using two weapons of the same type, and each hand usually has specific desired characteristics. But this makes it harder to gear up, as a Sword rogue has to wait for a sword to drop.
I think that it would be beneficial if rogue weapon specializations were combined. Combine the Dagger and Fist Specialization talents and allow Ambush/Mutilate/Backstab to be used with both Daggers and Fist weapons. Then combine Sword and Mace Specializations together (probably would have to only use the Sword spec ability). This would give each type of rogue more options when it comes to gearing up. A Dagger rogue could replace a Dagger with a Fist weapon and still play effectively.
You could do something similar with Warrior weapon specializations. Make the type of weapon matter a bit less in order to make it easier to gear up.
Feral druids really need a way to utilize normal weapons a bit more. Right now they rely on special druid staves. But the downside is that they can’t use normal weapons, and other classes can’t use their staves. Of course, feral druids have a problem in that they don’t share off-hand or 2H Weapon types with the other melee DPS (aside from 2H Maces).
The problem with healing paladins is that 1H Maces is the only weapon type that paladins used to have in common with the other healers. The other three healing classes share Staves and Daggers, which is why you occasionally see a healing Staff or a healing Dagger. However, with the recent change to allow all Shamans to use 2H Maces and Axes, I have high hopes that we will see some healing 2H Maces. 2H Maces would be a weapon type that could be used by three out of four healing classes (paladin, druid, and shaman).
In any case, my point is that making weapon types matter a lot hurts PvE, because of the way loot is distributed (random, specific drops). You either need to reduce the impact of weapon type, or move to a more “tokenized” model.
