Buff warrior's armor or health, otherwise warrior cant tank well in elite map now.
Rogue and mage can get over 300 dps in lv26, but warrior only got 180 dps. However, rogues and mages armor all go up to 800 now, warriors still only have 1000.

Some people may say with max gear, warrior stat is good tho. But mystic item is insanely expensive and hard to get dropped from chest.
