Basically the title. Life Leech Resistance has no proper use in the game. It basically make that serenity useless when you get that completion bonus. It’s a waste of mats/resources and time.
It can be some other CC resist, slow, trap or petrify. It can be energy regen bonus, it can be health regen bonus, it can be skill disruption resistance; anything but lifeleech resist or energy leech resist.
Yup, relics without specific class bonuses have wide range of completion perks, ranging from really good to WTF. With GD stash you can always “craft” relic with DA or % all three attributes but legit the probability chance is low and relics are the most expensive items to craft on top of that. So I like your proposal. At least something like slow is always welcomed for end game builds. Or % health, Idk.
GT “lies” with a lot of stats
easiest come to mind is ex attack/cast speed that is almost always 1%pt below the range GT displays, with a couple of exceptions - likewise with 5%global cdr on ex helms,
guessing it’s another instance of GT parsing direct from X vs what roll range is actually applied in game
