Change the trait imo its horrible even the old one before it had more purpose making it strike twice and extending the mortar skill duration's . Explosions traitline should be about damage getting a free orbital strike every 15 secs on a 50% target is pretty horrible with how slow it is. It needs to either improve orbitals actual damage by a lot or give it some sort of special function. The most you get out of orbital strike is hitting a pve mob with it or using it as a blast finisher no ones going to stand in this thing unless they want to die or are CC'ed into oblivion without any sort of cc break or cleanse.
