One stat only it was, I assume it hasn't changed. You need a pretty good item to be able to really make it good with enchanter.
Thorns there's a crusader talent that's pretty fucking strong with it so it might be useful for them. Pickup radius I thought was a WD stat but it's not that great either iirc. It's alright if you have the legendary that pops health globes, if that still exist, I remember it was broken OP so they might have removed it, but then again they were gonna removing the legendaries that convert damage into healing and they apparently didn't. Like quite a few classes have very strong talents based on health globes you just generally don't take them cause health globes aren't very common so pickup radius isn't particularily useful.
On transcendence yeah I guess I don't use enough spirit for it to be really good but could change my build some to use more spirit maybe(but then I'd need more spirit regen somewhere, maybe use a rune on builder that generates more). The scaling is better than I thought though, double checked it's .4% which I discarded as shit when I read the talent but then again I've been getting items with 4000-5000health on globes, that's +16-20 per spirit spent which is pretty strong. In fact it scales very well if you spend a lot of spirit and grab 3-4items with healthglobes as secondary, might revise my build some. My gear is pretty poop atm anyway, only like 60k DPS, it's pretty hard to find upgrades without legendaries, need to be luckier on +%dmg items and do an elemental build instead of trying to get crit/aspeed/critdmg since those are still hard to get at high values.
