Hunter GCD Reduction:
Ghostcrawler mentioned on the forums that a Hunter GCD reduction could happen because of the incoming resource change (mana to focus).
If Hunters actually receive a 1 second Global Cooldown (like Rogues) instead of a 1.5 second Global Cooldown the difference between good Hunters and bad Hunters should be more evident. Faster reaction times and faster thinking would play more of a role in the best Hunters. With our burst reduction in Cataclysm this change seems needed, but time will tell.
Arena Team: 1950 and 1800
My Hunter / Druid team hit 1950 and my Warlock / Rogue team hit 1800 this week.
I still feel like we are learning a lot with our Hunter / Druid comp and with his Druid getting some much needed weapons after hitting 1800 we were able to cruise to 1950 with a lot of his arena gear still being Furious. I expect when he is able to upgrade to Wrathful with a couple more pieces and as we learn to play our comp even better we will easily climb above 2k.
1800 has been the bane of my Warlocks existence as I have had the crappiest Item Level 200 weapons since I dinged 80. This week was quite rough as most of it was spent trying to figure out how to get my Warlock to 1800 so I could upgrade the crappiest part of my gear and really upgrade my character.
After switching between Warlock / Druid and Warlock / Rogue to see which comp would be the easiest to get to 1800, my lack of gear gave Warlock / Rogue the edge, even though Warlock / Druid is probably the better comp (although both comps are great).
I kept switching from Affliction to Destruction to see what worked better and Affliction ended up being the better spec which allowed us to hit 1800. Warlock / Rogue can definitely be a top tier comp, as we were beating 2k Rogue / Priest teams pretty easily and even found a way to beat Paladin / Warrior teams. The only team that seems impossible is Paladin / Death Knight.
My other friend has come back to WoW with a Mage and so we will most likely play Druid / Warlock / Mage in 3's as a form of Wizard Cleave.
Tournament Realm and MLG Columbus:
On the Tournament Realm the practice phase has ended and the real phase has begun. This phase will last a month and the top 8 teams will continue to regionals. The current standing is below (the "real" phase has just begun so there will be a lot of movement).
MLG Columbus is coming up in a week and will have 14-16 teams attending. This should prove to be some entertaining arena matches as their wont be the usual one dominating comp that every team plays but a very diverse field of comps. And there will be some fresh blood with about 15 new players who have never been to the tournament scene.
