This toon has DDoor too. So what's the prob?
If you want to take some specific occasion (like teleporting mobs, enclosed place),
I can do too (like the place you can't come back if you DD out).
But really, what is the point? Speed is useless?
Outrunning mobs is just a small benefit from getting high speed.
There's a lot more than that in speed.
(If there's a Feat which gives you +10% striding, I'll take it with this build.)
Btw, I don't have DDoor for escaping purpose.
Completing quests fast and easy, that's what I have DDoor for.
