I don’t even have WillPower lol and I’m on 6.4
I personally don't think you have the right champs to consider unlocking suicides. I got them once I got corvus & started arena grinding hard. Although I love suicides, finish fights quicker etc I've just finished up 7.2 expo the other day and had them off the whole time, turned them back on for a few days then had to turn them off again for SOP & cav EQ expo. I'll definitely be turning them on again once that's done but it is a massive waste of units, burnt in the region of 4-500 units just swapping masteries the past week or so, and I don't really do arena anymore.
@LeNoirFaineant The Skill quest has a passive heal block node this month. If you go in with suicides on and you're not immune to the bleed and poison or can shrug them off easily, you're going to die very, very quickly.
