Hope this is just a combo of damage boost and fort bypass, and that that combo is removed. And yeah, I think they should be able to bypass all that 180% as it helps level the playing field for newer players somewhat. That 180 still works on CR 80 sneak attackers, other champions, raids with SAers, mobs that sunder, challenges, etc., if there was some magic number that'd make you immune to it then we'd all just optimize around that number rather than ever have to deal with it.
Agreed on the either or, similar thing with second wind. I can't see which champ has it in a sea of mobs and it's sometimes very hard to see when it triggers, either tone down second wind or make it much more obvious.I would suggest giving champions EITHER complete fort bypass or damage boosts but not both at the same time. Having both at the same time creates the randomness that leads to one-shotting. Alternatively give the champion armor piercing of some type that doesn't exceed 100% fort bypass so people with high fortification have some benefit from it vs. someone with nothing or with only 100%.
I would even go so far as saying you can raise the damage to previous levels if you adjust this.
And again armour piercing is bad, just build for it and it becomes a digital thing. Do I have fort that works or fort that doesn't? That's what happened with the sneak attacking mobs that could bypass their CR in fortification over 100%, we just built toons with 100+ max CR fortification so we never saw it.
