BIOWARE SUCK. This game is so boring! aside from warzones, heroics, Operations, dailies, levelling, gearing up, world pvp, heroic quests, class quests and companion storylines THERE IS NOTHING TO DO! As for all you fanboys saying that this game has an awesome storyline? well it doesn't. I don't care about your opinions and i'm not basing this on any fact or backing it up since i space barred every quest i did, but believe me, i know that this game sucks! I mean really guys, since this is an MMO it's obviously just a wow clone anyway. I dare you to name one other MMO or RPG that had quests, dungeons, raids and pvp before WoW, i mean its just so pathetic how unoriginal Bioware are. The PVP in this game is completly broken. I only win about 50% of my warzones, i can't believe how ridiculously unbalanced this game is. And after subjecting me to that horriblly challenging pvp experience, i can't get a full set of Battlemaster unless i go and play MORE pvp... What the hell is wrong with you Bioware? i don't pay my sub to work for gear FFS. OH! and WHAT THE HELL is with them giving us Oceanic players servers with lower ping!? HOW DARE THEY! if every other MMO is smart enough to make us play on American based servers then why cant Bioware wake up!? And then to top it all off, they won't let us transfer to these new horrible servers yet. I have to keep playing on a US server that for some reason is waaaaaaaay way worse than all the other US servers i have played on in other games. so GG Bioware, there is no way i'm going to resub to this horrible game.

Will future raid teirs include extra mechanics in heroic / nightmare modes, as opposed to just reducing the enrage timer?

I'll be honest i'm not having too many problems with jugg tanking, sure its harder than other MMo's but it reminds me of warrior tanking in Vanilla WoW and BC, aoe is ok as long as your dps let you LoS pull and are intelligent enough to only use there single target abilities on the mob you are targeting (wouldnt target of target be great about now? -.-), single target i have noticed i will lose threat every now and then but my taunts are normally off cooldown by then, it keeps me on my toes so i'm enjoying it. That being said they could deffinatly do with a threat boost but i wouldnt say they are game breaking either, the only reason they seem unviable is because other classes have a stronger tanking ability at the moment. as long as they dont give tanks a 500% buff so they can hit once and AFK like WoW did in Cata i couldnt care less how they change the class
