None of this is terribly controversial. Sins are fine in that they are in the middle of the pack in ranked. Top Sins can still get top ratings, but it's easier to get a higher rating with a AP PT, Smash mara, or operative healer. Sorcs, mercs, DPS Juggs, need buffs to be in line. Some AC's, like madness sins and conc operatives are currently worthless for ranked period. So they can either tune down the top 3 advanced classes a little bit, or buff everyone else up to the same level.
