I think the next 'testing' might involve Qeynos revamp. If so, that will need characters level 10-90 for testing of the racial quests. Most should have toons in that range but they may put in a buffer.
I would like to see a buffer that buffs in 10-level increments for that! That way I can try each of the racial questlines by rolling a different race and buffing to the level needed for the next series of quests
