Vampire characters will suffer an extreme loss to their Health Recovery with the PTS changes to "Battle Spirit" when reducing Health Recovery by 50%. Would it be plausible to have a "which ever one is greater" scenario for Vampires characters e.g. Stage 1 ("Battle Spirit"), Stage 2 ("Battle Spirit"), Stage 3 ("Vampire -60%"), and Stage 4 ("Vampire -100%); The proposed change would still achieve the PTS objective to reducing the overall effectiveness of Health Recovery in PVP content game play; BUT it won't completely wreck Stage 2/3 Vampire character.
Vampire characters operating at Stage 2+ already suffer other penalties for advancing their stage. I simply don't feel the extra penalty is warranted; therefore, I hope you consider the "which ever one is greater" scenario to lessen the impact on vampire characters.
