PvP need to be rejuvenated, its current state is sad and I hate to see it like this. Might be a long thread because I have a lot to say on this topic.
With these new additions to PvP mid-season (baseline resilience at 65%), the game still suffers from being unbalanced. This wasn't a magical fix, in fact it just frustrated a lot of people. You still have certain classes over-performing and under-performing in PvP as always. Also the downscaling of item levels in PvP should help, but an argument could be made for the other side as well. I thought it was exciting to find a perfect balance between PvP and PvE gear in PvP, sacrificing your survivability to become more powerful was a fun thing to do. Now you don't really have that freedom, if your class is weak you really can't do anything but deal with it.
No gear progression, this is a huge problem. WoW is an MMO, and a staple of an MMO is gear progression, this is what people want and strive for. Right now there is no gear progression in PvP. Capping for conquest doesn't count as real gear progression because it is effortless, and everyone and their mother has full tyrannical. Even if you aren't in full tyrannical there isn't really much drop off anyways if you're a casual player doing battlegrounds. Why not re-introduce the rating requirements to buy PvP gear like in wrath? Have people work towards something and feel good about getting a new piece of gear they unlocked.
Right now there is no reason to play arenas or rated battlegrounds because there is nothing to work for. Get gladiator? Most people won't get gladiator anyways and see it as unattainable. Usually you could have played arenas to unlock new gear, or even hit 2,200 and get your tier 2 weapons and become more powerful. But of course that is no longer available, gear progression is gone in PvP. Blizzard expects people to be self motivated to play arenas for fun, but it isn't fun in its current state, it is more stale than ever. I personally don't have the urge to log on and do arenas anymore, no reason to do so and nothing to work towards. Why log into WoW and try to find partners when you can goto a competitive game like LoL and quickly find a game? But this thread isn't about LoL so I'll try to keep it on topic.
What about the people who have a hard time finding arena partners? No achievements so you can't play with the good players, when in reality he could be a very skilled player. If you got a high rating once then you're pretty much set, even though those ratings are completely invalid. Someone who gets 2500 in wrath could be playing like a 1700 player today, I've witnessed it. This needs to be fixed, people who didn't have the opportunity to get a high rating one season are left to suffer and it shouldn't be like that. Arena achievements and statistics should be wiped at the start of every season. This would encourage more people to play arenas, because those statistics and achievements are invalid and useless. PvP needs to have fresh statistics and achievements every single season. There are probably tons of players capable of getting high ratings who log on, fly around the main city and log off because they can't find a good team to do arenas, all because people want an achievement link.
PvP is in a really bad spot & arena participation has plummeted for a reason. I hope Blizzard would do some of these things and give life to PvP once again, because right now its dead.
