I'm not sure how Hunters would get changed positively at 20.
It's the opposite end of the coin from Rdruid - they're both balanced heavily around endgame with their pvp combat number scaling, which just coincidentally happens to fuck up 20s.
All they would have to do to hunters is just move Nerd Shield to 21 and move the heal to 21... they can keep all of their silly ass 2 finger dps, nobody cares about that... it's just that and being unkillable/able to make deepstrikes to healers with ZERO concern about death from tier 2-3 dps.
But, that's just a dream.
There are good Rdruids and there are A LOT of shitty ones... twink or not... good ones are hard to deal with.
