I have a genius solution to Banneret being awful.

Just bring the warlord back. That's all.

I have thought long and hard about this and concluded that what I already wanted is the fix this time. Just add an entire class. Only this one, not the one Jonathan wants, because Jonathan wants Swordsage and Swordsage sucks. Warlord is cool though, and that's why you should add Warlord.
