Tanking is no longer something you are punished in other areas of the game for taking up.
You might also be seeing a situation where tanks, either by the type of player they attract (tanks in my experience tended to be much more focused players, giving a lot more time to the game than casual dpsers) or by the mechanics of leveling as a tank (with healer/dps companion you can mow down groups faster and kill elites easier) so you might just be seeing an over population of 50's tanks simply because they are faster at leveling up than other classes.
