It's clunky, more or less all of the 5.2 trinkets we want scale with haste which the 5.0/5.1 trinkets don't. Atm I'm at 44% haste fully raid buffed, if estimates are correct we'll go up to 50% raid buffed. 50% haste vs 30% haste is going to matter a lot with the 5.2 trinkets, if you don't got a lot of haste I'd think the 5.0/5.1 trinkets are better but with gear you really should use the new trinkets.
