Not so OP really... perhaps annoying if a team of 5 was running em on turret boats or something... but phasers are more annoying in that case anyway.
Honesty with things like the BFI doffs... the Torp Doffs... Tech doffs... Attack Pattern Doffs... Flight Deck Doffs.... the sub nuke doff has a really really high opportunity cost. I would likely not slot them if someone gave me 3 purples.
Oh yes this feature must be nerfd..... In the case of 2 or 5 ships with this dooffs stakt this by all ships in every ship goes three of this doofs... with FAV from the cruiser and rapidfire from escorts ....... I mean SNB without END... For example In combination with three Scince Ships and his Feature SNB... NO!
This DOFFS are absolutly overpowerd. This Doff's not erase one Buff no they erase ALL Buffs.
My mean is. Set the Chance from 0,5% to 0,01% or make this Doff erase max.one Buff with the same chance.
