Phantasm/Clone health
Are you sure about your pve numbers? They do not follow with what the patch notes stated a while ago.
Phantasms used to all have the same hp. Pvp was increased by 55%, and pve by 270%, making the factor from pvp—> pve = 2.783.
Your numbers give a factor of 1.7. Unfortunately, both your defender and normal phantasm numbers align with that 1.7 factor, so it’s looking like a stealth nerf.
Retested it in LA on test dummies, cursed shore, and coe explorable (all lvl 80 areas). The numbers in OP still correct. I even equipped signet of illusions and phantasm health increased by exactly 50%. Activating signet caused health to immediately drop to 5,969 & 12,794 for the phantasm & defender respectively.
Next, I had a friend join me in both downleveled and lvl 80 areas and we compared the health values I was seeing with the number showing on his health bar. In both cases our numbers were identical. This only reaffirms that the health pool values I’m seeing really are correct.
It might be a bug.
