Imo pallies are frickin hard to kill has well, and nerfing travelshape would be just lame. It hurts every spec, not just resto, not to mention druid abillites already are lame for just working outside.... None of the other classes that can spec extra speed get it outside only..
And escaping.... well, as long as a resto can outheal twice the damage I pour out, when standing still behind him doing all the damage I have, it's not the escaping that's imba. Besides, pallie judgement, druid roots, warrior snare, hunter snare, rogue poison all make travel shape less usefull already.
