And the problem with resistance is that in itself it only resists damage. The chief problem Regen has in this material is that not only does it have very little native damage resistance, but that it also eats all the debuff (-recharge, -heal, -regen, -HP, -recovery and etc.) attached to that attack, without debuff resistance. And unlike defense, and to some extent resistance, debuff resistance mostly can't be built for with special enhancements or set bonuses. I took Ageless on the regen scrapper I mentioned (tanking regen brute has Barrier) and it does not cover all the bases. Ideally Regen should shrug off all these debuffs like Electric armor shrugs off endurance drain. Again, for an armor set depending on click heals, the availability and usefulness of those click heals should be preserved. In the current level 50 game it's too often left with nothing.
