Phase door is a shitty teleport that will get you killed
The big deal about actual teleport effects, like from the rune, amulet, or staff, is that they have a
minimum range, which is about a hundredfold more important than their maximum. A PD rune or effect, unless it's controlled (and sometimes even then!) is entirely too likely to land you right beside whatever you just tried to escape from, or, at best, still within firing range of it. A teleport effect
won't, except in very rare circumstances in very open areas (of which there's like, maybe two in the entire game).
Teleport might land you in a
new clusterf- ah, problem... but it's pretty much sure to get you out of your old one. Phase door has no such guarantee and is entirely too likely to bring you
closer to whatever you were trying to get away from.
You might be able to get by with a movement infusion, if it's a good 7-800+%, though. They're like PD, except incapable of inadvertently moving you toward the enemy and considerably more controlled. Can't get you out of being surrounded, but better in every other way.
Seriously though, phase door is basically crap as an escape method. It's got two uses, and then only with the controlled
talent, not the rune or item activation -- short range movement, to get yourself away from melee enemies or close to ranged ones*, and for targeting escortees, to move them out of a gangbang of some sort. To re-emphasize,
phase door is not an escape method. Do not try to use it as one unless you have absolutely no other choice, because it's probably going to kill you if you do.
* Movement infusions are a thousandfold better at this.
