Ok, so I'm 70 now with near full epic gear. Yeah, I know I don't have even close to the best, but it's definitely beyond your trashy quest gear now... and I have 3 major gripes atm:
1) Mana/Aspect Issues
Essentially, when I'm using Aspect of the Hawk, I have damn near ZERO mana regen it seems.
I can never seem to justify using Hawk for many situations at all. With viper on, my mana regen is pretty good (although It's still easy to run OOM without chugging pots or asking for a judgement of wisdom).
So basically I end up asking for a judgement of wisdom buff to be kept up on the target, and never take off viper. Why?
A) It's more fun to keep up a constant shot rotation without slacking off on DPS due to mana issues, and
B) It's far less bothersome.
I really can't seem to justify the use of aspect of the hawk when the dps difference between hawk and viper doesn't really seem that huge, while the mana regen issue between the two is VASTLY different, and using hawk will run you OOM in no time. I guess I could see myself using hawk down to 50% mana, then asking for a judge wisdom + switch to viper, but the fact that I go to 50% mana in 30 seconds or less as is, just seems meh..
As far as pvp is concerned:
I have roughly 6500 mana right now, and I don't see that number inflating a whole lot with my pvp gear upgrades. Do you know how long it takes for a team to mana burn me if they get a good opportunity? About 8 seconds. Granted, I typically focus priests and warlocks first a lot, and I'm viper stinging either one that isn't pillar-fagging me (usually the priest, though). However, if I catch a CC out in the open such as fear, it just takes about 4 mana burns and I'm completely OOM. And let me tell you how effective of a team player a hunter is that's oom.
Even with viper on, it takes forever to get enough mana back to do anything meaningful, and once you do start wing clipping/viper stinging/trapping/flaring/etc... your OOC mana regen goes right back to suck. And once you DO get that low, FORGET about ever changing aspects into something else. Want to put on monkey to help tank that rogue? Sure, go ahead, just don't expect to be able to throw down new traps or switch back to viper, cause you're stuck in it until you drink (which isn't happening, cause melee is on you, remember?). Need a quick cheetah to get away? Hope you have the mana to switch back to viper so you A) don't get dazed, and B) Can get start getting mana back once you get into a better position.
2) The best arrows require honored mount hyjal faction.
Now normally, I wouldn't care about this. People dump a lot of time and wow gold into progressing for PVE. That's fine. What I DO care about, however, is the fact that good pvpers who have access to these will have a step up above any non-raider. Technically, this is a blatant imbalance that needs to be resolved. The difference between the Karazhan arrows and the timeless arrows are a big enough difference to equate to about 9 or 10 BT-quality gems vs the standard blue quality gems in terms of raw DPS stats. There needs to be specific rating-required arena ammo that can be purchased, as long as you meet a specific rating (team and personal) requirement.
Once all other areas of gear are maxed out, the difference in damage between 2 hunters using karazhan arrows vs hyjal arrows can be enough to decide a game. This obviously needs to be addressed, hopefully at least for season 4, if not sooner.
3) Why does my ranged weapon not show up on my back?
I guess there's some sort of coding conflict with capes vs ranged weapons? We should at least get an option. Hopefully Blizzard will be able to resolve this issue and allow the display of your cape and ranged weapon, in addition to your melee weapons when not in use. Also, I find it disappointing that people can't see my quiver on my back. Only I can, and that's kind of lame. :(
