With the agility that a druid or warrior has at level 80 while naked, given a full tanking spec for each, the druid actually leads on avoidance by over 1%.
Druids scale equally or -- wait for it -- better (ZOMG) than warriors or paladins for avoidance! Not sure where death knights stand with their high parry values, and that may be adjusted in a tanking pass.
