You are adding more HP into the game, adding more base mitigation and adding more mitigation to heavy armour, which is already the meta in PvP currently (21% mitigation for 7 heavy). Now, instead of fighting 40k hp Wardens, we will fight 50k hp Wardens, they will have more mitigation due to the heavy armour changes (21% to be exact), more hp, more max stats (resulting in more heals) whilst still retaining the same proc sets and damage they currently have on live (no adjustments to Malacath or proc sets). The "nerf" to Alessian has done nothing as you barely reach the new cap anyway and % modifiers such as Major/Minor fortitude remain the same.
Not only will this make CP PvP completely unplayable, it will also greatly affect No CP PvP as the extra stats, hp and mitigation is being added as a base to all characters and not connected to the CP system.
Please reconsider the changes you have proposed ZoS otherwise PvP will be completely unplayable.
