it has an accuracy check (it must I assume
as it procs like crazy pre-4x8) despite not taking enhancements so it’s just missed more than anything. The end drain isn’t actually all that bad, but you’re not getting a whole lot out of it for the end it takes. It’s just lackluster at the end of the day. Especially on Mm where the recharge isn’t as useful as say on a corruptor/defender from FF. Usually 3 slot with end redux, ff, and KD.
Sonic is my favorite set since it was released- I do a LOT of Sonics (4 cor, 2 defs, 2 controllers, 1 mm) and most have it, but I think for a MM it doesn’t do enough. It can make a scrapper a better tank though. i do like FF too lol
