Isn't that how you raise taming before 90, tame, release, kill, repeat? LOL
Well, that's $10 bucks down the drain(cost of 1000 sovereigns).
I never really wanted it as a regular pet anyhow. When I started back about a year ago, I saw it with charger and that unicorn and thought they were ethy mounts. I was really mad and ended up buying a charger anyway, just to have an ethy before I got my horse ehty through vet rewards and gave the windrunner to my tammer. She trained it(skills, not percent) but was nothing but a lesser tank(had over 500 hp or str I think and pretty good resists for a 1 slot) but it only did 1-4 damage.
So, even with 100 in all its fighting skills, it took forever just to kill a bear or something. I tamed a regular ozy(not frenzied) that one hit most regular animals and wasn't even trained or skilled. Because it killed things so fast, it hardly ever got hurt.
Now that I have better pets, I really had little use for the windrunner and gave it to my secondary account tamer(for mainly transferring pets between chars on main act and rezzing). It was this secondary tamer that was using it on Ice Island(dagger) while training his taming.
If you read all that I salute you.
