I find sentinel is waaaay better than dawnblade.. The only good thing about dawn blade is its neutral game. The super sucks in terms of damage in PVE, and in PVP it's very hard to hit your targets and its very easy to dodge. And if you want to use a slightly better version of the super, then you sacrifice the neutral game. It doesn't last as long as it should, and the slight tracking should be on both trees no matter what.
