Evasion is irrelevant, but using Featherfoot is nice sometimes. For example, when you see a big mob charging up a strong tp move, you can use Featherfoot to avoid it because they hit hard and you usually can't block TP moves anyway. In case you don't know, Featherfoot is a low level PGL ability, so it's pretty easy to get. It doesn't work everytime mind you, but it's always nice to evade that 1k move coming your way when you can. A good example is higher level moles: when they go underground I always use Featherfoot, and watch people in my party getting raped by the TP move with a smile; it hasn't failed me many times, so you see, it can be worth it.

As for stats, what the others said. Personally I have STR > VIT > DEX > MND but that's only because I solo a lot and I need the STR and DEX to do damage. I wouldn't care as much about DEX if I was tanking all the time. Once Paladin is released, I'll change and focus on tanking 100%.
