Casted heals we only have HT <- 3sec cast 30k heal and no hots.. only reju.
Yes, shifting roots and slows goes way back in the game's lifespan but I think it's a bit unnecessary. With ferals being hybrids they probably have the largest skillset of any melee class at their disposable while they are rooted. You know, casted heals, cyclone, hots, etc. A rooted Feral druid can still make himself useful; a rogue or warrior -- not so much. I think freedom-shifting is a bit of an outdated -- and unnecessary -- mechanic.
