Well, time to wade into the PvP epics, or "welfare epics", controversy. Basically, many raiders feel that PvP epics are too easily available, and are having negative effects on raiding. For example, most DPS will sport the best PvP weapon, and PvE weapons will be sharded when they drop.
First off, I am happy that PvP is another way for a player to advance their character. I like raiding, but you shouldn't have to raid in order to progress. But there are two main issues that I see with the current setup of PvP rewards.
First, the decision to make the PvP sets recoloured versions of the PvE sets was a bad one. It cheapens the accomplishments of both sides. PvP armor should look visually distinct from PvE armor.
Second, and more importantly, PvP rewards seem to lack the same sense of progression that PvE has. In PvE, you have to go through T4 content/rewards before you go to T5 content/rewards, and T5 comes before T6. You can't really skip vast amounts of content. I mean, the reason I don't have any T6 is because we're still working on T5 content.
PvP really seems to lack this. Alts in blues are now sporting S3 gear. In some manner, I think you should have to pick up some S1 gear before getting S2 gear and then S3 gear.
Someone who is in full S2 and with a 2000+ rating definitely deserves T6/S3-level gear. She shouldn't be outgeared by raiders just because she chooses to PvP. I'm just not sure that someone with a 1500 rating should be allowed to jump straight from blues to S3.
Perhaps a system where you had to have the S1 weapon and 2 pieces of S1 armor before you could purchase S2 armor would be good. Then you'd need some S2 armor and the S2 weapon before you could move on to S3. A sense of progression, of moving up steadily, rather than making large jumps.
This would also help the raiding side, as people wouldn't be able to PvP just for the weapon.
The old PvP Honor system, for all its flaws, provided this sense of progression. You got your blue boots and gloves at a certain rank, and as you rose through the ranks, you got better and better gear, eventually earning epics. But there was no sudden jump. A player with a Grand Marshal or High Warlord weapon had earned every piece of armor before that. You couldn't have a player with blues and a Grand Marshal weapon.
I think that PvPers shouldn't be allowed to skip tiers so easily. Having a more natural gear progression would also work well in PvE. A player might go from a T4 weapon, to an S1 weapon, to a T5 weapon, then to a S2 weapon, instead of jumping straight to the S2 weapon.
So those are my two issues with the current PvP Arena reward scheme. The armor needs to be more distinct from PvE armor, not just recoloured, and the rewards need a better sense of pacing and steady upgrades.
