I find that FTL makes the game a little more fun, by virtue of being just slightly less irritating to play. With a non-FTL setup, I have five keys to define the leaders, F1-F5. With FTL, I've bound one key to my mouse5 button, and switching leaders is far more fluid. It's also foolproof; I never hit the wrong button.

My druids are my only FTL group right now, but I'm going to change the others over too. It's the only way to play ... for me, at least.
