Which monster do you like the most in Heroes 5 (level 6)?

They move pretty fast... they can reach the end of the map in two turns... And even the fastest units can't cross the map in one turn... They move only slightly slower than paladins... Unfortunately, they don't have a tournament attack... But they have incredible defense, a lot of hit points, and while their attack might not be amazing (though it's decent), they have roots... Gather a large group around them and bind everyone... Then let the ents attack, they're like tanks anyway...
