I personally think Damage mitigation is a hot mess in PoE. It wasn’t ‘found out’ simply because of lack of ‘infinite’ end game levels, where the META builds will be apparent to the run of the mill builds.
ES (Energy shield) is too easy to scale, made worse by last few patches that greatly increase quality of item, which also scale ES to be obsurd. There is also many things that can regen, charge ES, on top of converting life regen & leech to ES. Also a gem (Discipline) that further increase ES, on top of a jewel (watcher eye) that further leech or regen ES if you have discipline applied.
There is NO equalivance to life builds. But but life build is suppose to mitigate with armor, isn’t it? 4 problems.
- Armor is hard to scale
- Armor works only for hits to you. So ground effects, aliments, Armor are useless
- Armor only works for physical damage type. ES act like life, so imigate all damages.
- Armor imigation is poor, It is not converted to Damage reduction% as ou would have thought, but rather as a FIX reduction, which means it scale badly against big attacks.
Then there is a evasion builds which is the most dumb of all, if you enjoy being one shot & lost progress. I can go on why its poor, other than the obvious that you eventually get hit, & you will die without huge life/ES pool. It ONLY works for HITs (like armor) & again only for physical damage.
In fact originally Diablo 3 used to give evasion for dex stats, but due to keep getting ‘one shot’, players asked Dex to scale with armor, which they eventually did.
In Diablo 3, armor scale against ALL damages (as a damage reduction%), which while I inially did not like the idea, but its far better for balancing.
If you ask me, I think WARDs and Energy shield should be a converted to (All) Damage reduction % & not add to helath pool, and armor is also (All) damage reduction, so its easier to balance. Life is always key. but you can build armor or ward builds or hybrids.
