I think Blizzard 'still' act too fast. Let the game flow by itself for at least 1 more season. I see the most balance of SC2 right now where u r rewarded for havin skill instead of relying on OP race (yes, im talking bout bunch of patch-zerg pro-player). 

Zerg roach bane bust will be more powerful as 1 more weapon to defend (hellbat) is going down. This is the only thing I don't like bout  current SC Meta at the moment. So skilless and yet offer zerg the chance to recover in the late game scenario too when bust kill enough worker(usually it does). Well, too much hellbat vs hellbat is not fun either

Warp prism is a very good unit. A buff sure encourage (the lazy & un-innovative) pro-Protoss player to use that unit more often. Would love to see more multitasking from Protoss. Reaver-Drop is kinda exciting in the early days. Saw a good game from P where MC use HT to guard Carrier and Carrier to zone out for HT while always using Oracle to use revelation on enemy unit. Not to forget, only few player like Rain who use storm drop  which is highly efficient. Other pro-Protoss player are such a baby, always stick to the same dead ball composition and complain the lack of unit to play with.

Still waiting for a representative of Protoss player for SC2 like Bisu did in BW.
