But why nerf Wraithguard, if it is no longer stacking with Evasion anymore? Ghosts will be too fragile for the most of the battle if it is 3% or 5%, and adding a base reduction to it will defeat the purpose of 'only usable when low on HP'.

Don't nerf it to dust is what I suggest. Wraithguard is still a 'chance to trigger' like Evasion, but using LUC + RES. And costs 3M. And can be stolen. And lasts for 3 rounds. It's not a passive that triggers on every damage you take.

Just put it at 1% damage reduction per 2.5% missing HP instead. We could even ask for Dev to add a condition where Wraithguard can't be used if you have more than 50% HP. No biggie.
