Heh. Does anyone play the Druid for anything (stealth, perhaps) if his vine summoning isn't all that great?
Wardens make for a wonderful elite troop. I haven't seen anything wrong with bless effects on them, since they seem to be the perfect platform to build on; they're fast, stealthy, and hit a lot. Air definitely seems to be a good choice; I've already seen the power of taking a very high Nature
Not to mention the Warden Commander with Heroic Quickness tends to decimate things quickly; I even had some luck making him a flanker-attacking-rear instead of purchasing the very expensive Knights.
