Stack on-kill Sigils
I don’t like that idea too much. There’s no point in your change really just use the stack on kill sigil you want (condition damage, power, healing power, or toughness) and enjoy.
Also, I like being able to in dungeons get 250 extra power (assuming I can keep it) then switch to my Axe/Mace for 10% more damage and about 6 extra might from swapping
