@sener - you do realize that by delaying T5 Warmane actually did exactly what you said - leveled the field for all players. And why would Outland's launch be "out of the blue"? It was well communicated, with constant 15k online and 1.5k on queue every evening. People were all well aware of the competition, they were leveling, gearing, and raiding accordingly.
Basically, you're expressing concerns which Warmane already addressed from launch. If there are players who still haven't cleared T4 by now and aren't progressing T5, then that's purely their fault. The realm has been out without T6 far longer than retail, and with far larger population. As I said in my reply above, progress-wise it is still early for us to have T6, but that's our fault entirely - not Warmane's.
