Feats to what end though? If you can already get most of your combat power from other sources built into your class, why even bother getting feats (most of them are fairly useless btw).
BTW, a side note on that, should I get mithril armor or addy armor on my kensai 20 pure? I do have an extra feat sitting around but what will armor do to my WF fighter really? (a measly 5 extra AC points lol)
