Well some people just always have to complain! Heck even if you want the achievement, I don't think it is a bad idea or even offending to offer a character pack for it......
It really pisses me off if some Idiots just want to stop such things just because they are frustrated or jealous! He didn't offend anyone of you, did he? (dedicated to the fellas who sent the pms).
If I would say I'd give a thousand dollars to the nex one who writes me a pm, lots of ppl would hate me for that. Ok there's only one who can get it but if I wouldn't give anything noone would get something..
Think about it!
And what do we learn: Some people are idiots for no reason!
