Holy crap Blink is game changing even without Temporalis
I took out some spirit gems to try out blink, took a single herald reservation node, and tried to map with blink to see what is the big deal.
Ok it's game changing. I was able to hop over ledges instead of walking over it, I could blink through breach packs, heck I actually bothered to blink up a ledge to open a chest because I didn't have to walk around the ledge.
Everyone should try to get the int for blink if you are remotely close to the right side of the tree, even offhand is good enough for weapon swap. But if you can afford to have it always on it's really useful for tactical retreats.
