I know I deleted one at 2-0 PK record at hero in ~100 hours for example. While no one could touch me, I couldn't kill anyone either.

I later rolled and deleted another one in Battle, people used this OP tactic against me again.

Flee/quaff.

That's all it takes to get away from a dexy ranger.

In a modern CF, you can be an untouchable God of tanking, but unless you can preempt/prevent flee/quaff, you're not killing anyone. Sad but true.
