I’ve seen other people disagree with this already, but I’m of the opinion that other tanks need pure consistency with interception, rather than nerfing Strongholds. Aberrant setups can be nerfed, but so many tanks are bogged down by having to “waste” (as in, a boring, but necessary slot) their artifact on the ability and the ones that don’t have to become extremely powerful. Nerfing 3-5 abilities that would admittedly be hideously broken with 100% natural provoke is worth it to buff dozens more into viability from uselessness, and makes early-game variety so much fresher, as newbies aren’t forced to start with a Stronghold.
Make the AI sometimes “forget” to provoke (like it sometimes already does), to make Emerald Paragon/Frenzy Ghoul not required, or make a character perk that can bypass enemy provoking with a chance. The reason for all this song and dance rather than simply nerfing the Stronghold is due to the fact that without an absurdly excessive malus like 500% damage taken, 100% Provoke being given to it makes the ability boring, yet necessary, no matter how much you nerf it, but it -will- make things more annoying.
I feel the Stronghold ability stands in a weird zone where it does not “feel” powerful, but is excessively strong: nerfing it would mean you would continue to need to use it, but feel worse using it. Other alternatives are raising the base provoke consistency (for example, from 65% to 75-85%, though I don’t know exact numbers) or making failed Provokes intercept a portion of the damage, making it not totally reliable, but giving that vital pressure relief to new players who are forced into using a Stronghold for the first 50 hours of the game because their creatures get annihilated otherwise, by attacks that “escape” normal provoking. Being strong enough will still allow you to one-shot key monsters being protected on the enemy team.
TL;DR: I strongly disagree that Stronghold needs to be nerfed, but other options need to be better, to allow new players to open up their options early on, and keep Stronghold a viable, good-feeling choice, without being forced on many builds not using things like invisible dancers.
