you tell me this now?

I found this on WoW Insider a few days ago about T13 set bonuses (the proc being off Arcane Shot):
"The challenge that MM faces currently is that it can do more damage by hardcasting Aimed Shot than by using Arcane Shot as a focus dump."

Yeah, i've been theorycrafting on my hunter for weeks (if not months) now and you just tell me that now?  I mean, i've seen one or two people advocate hardcasting Aimed Shot while Rapid Fire is up, but then my own work at the Training Dummy and other people discredited such theories.  The trouble with using Aimed Shot as a focus dump is that it has a reallllly long cast time and a reallllly high focus cost so that means that you are capped the entire time you are trying to cast it (assuming that you don't get interrupted or have to move, mind you!).  Aimed Shot is completely impractical, Master Marksman usually procs just as the mob is dying, and until it's added to the Aspect of the Fox list...  So how???  I don't even know how to begin to try to master it.  How do you force an elephant into a slot left for a mouse?

Notice i used "cast it"?  I want to be able to say "shoot it" or "aim it", something that sound like an actual Hunter, but instead Blizz has made us more like casters than ever before.

Arcane Shot...i don't know why i hate it so much, i just do.  It's like Serpent Sting before it was buffed, completely worthless, or at least nearly useless, and the "experts" can't seem to decide whether it should be spammed or panned.  Hunters aren't casters, we aren't meant to do magic damage (#1 reason to take mana away from us, but now you want to make us more like casters???  Which is exactly what Aimed Shot, Cobra Shot, and Steady Shot do).

#1 reason i am considering quitting WoW...is that i don't like feeling this way about Blizz, as if anything i like about my class is only going to be taken away from me, and anything that i don't like about my class will eventually get worse, too.

Another example of this:  Raid Finder will only be for 25 mans and will yield no VP.  There's no reason for me to go in.  I get instantly DCed in 25 mans, it's hard enough staying connected and viable in 10 mans (actually, it's impossible even with my video settings turned down ALL THE WAY save for Particle Density).  And the only way to get VP is to do defunct raids or 3 heroics that i don't know if i will be able to do or if they will be like ZA/ZG and you have to outgear it for it to be fun, fast, viable.

Why do i even play this game anymore?
