You do realise it stacks ontop of it right? I still feel like you’re making a mountain out of a molehill about it. Sure you could compare it to 5% of anything else and get upset about it for no logical reason or you can look at it like a little bonus that helps facilitate it on brand with the warrior themes as it not only gives your allies a health buffer to take more punishment it also spurs them on to fight through it and heal from their renewed onslaught. It’s still useful in all game types as you’re almost always on target when you use it in pve and in pvp both the leech and the movespeed help facilitate being aggressive during it for a higher return.
Sure it’s a little embellished but it’s a pretty cool addition, sure a 5% flat absorb/dr would be more practical but this is still nice too.
