The only good thing about top tree nova is the grenade improvement but who is going to use that now that hand held super nova and nova warp are there? The only good thing on bottom tree dawn blade is extended super with each kill. This could have been done with an exotic like the titans and Hunters have (Considering there are no decent exotics for Dawn Blade specifically yes I am excluding the chest piece for attunment of Grace as that is a support class) Phoenix dive is useless. Melee that makes enemies explode on kill is lame compared to top tree Dawnblade which has 3 benefits, (burn damage, faster movement and 100% in air accuracy)
