Yes BS is a good potential damage and extra threat. I am always smiling after any hit with BS.I dunno, if BS is active... BS + Death Spin alone does significantly more. Reborn doesn't even really GET an ender/finisher now that I think about it x.x
That's fit to the patient gameplay but not always has the room to pick it up.
To bo honest I do not use DS ender anymore as I found 212+4 better for me.
