I'd like to start a thread about the Defender class. I've long found the class to be full of annoying skills that don't make the class that worthwhile. I've often felt the class should just be rolled into the warrior class and give the warrior a more defensive branch.
First, "Guard" is next to useless. It is far too dependent on priority (something we have little control over) because as soon as the guarded unit takes its turn the defensive bonus is gone. The defensive bonus--whatever it is--should persist until the Defender's next turn for this ability to make any sense. Something like a straight defensive bonus of 5 or 10 would even be better than the way it works now.
I'll post some more thoughts as I go, but please add suggestions here.
