I'm not sure if anyone has already suggested this but... I think it should be nice if all non monk tactical feats DCs instead of X + Str were X + "Stat you use to hit". This should give a bit more options to finesse builds. Still, STR based character would have a higher DC, as it's easier to buff up this stat than any other, but at least some builds could use this feats and items that buffs these feats and reach some useful DCs.
About the combat log, I think it should be nice too if you could change that filter with "Damage Dealt", "Incoming Damage", "Friendly Effects", and "Enemy Effects". That way we'll be able to keep track better why we're instakilled sometimes (hate those 23942739 lines on the chat log about losing buffs) and other stuff.
