Does this count as "Ninja" ?

Hey, so i made a Mechanar HC group with my friend and we reserved the Primal Nether (last one i needed to make deep thunder)

However: I forgott to put on ML on the last boss.. And a rogue named <I should read the Forum rules> (who was well aware of it being reserved) needed on it and won it, instantly left the group and hearthstoned.


Having kinda a annoying attitude as well

I mean, in my opinion its somewhat ninjaing when everyone was agreeing upon the nether being reserved before entering the instance, we wrote it several times and got their acceptance. It's partially my fault for missing the ML but it kinda sucks anyway.

So, dont trust Alliance rogue named <I should read the Forum rules> people. Thanks
