I agree with this. I missed this but loved 55 in game but can't get him because I missed the window.
As to those who are against it, why be so nasty/antagonistic to other players who just want cool things in a great game? Surely more people getting what they want in a game that is on the decline in numbers would be a good thing to keep people in game....? Why do some people think "Oh you didn't support the game then, so you don't deserve it now," when people just want to enjoy the game in all aspects? One person having what you had "earned" by paying for it doesn't eliminate the fact you were awesome to earn it - it helps keep the game going when people pay for stuff.
There's a few times I've felt this game is stingy. Get people back, get people subbing, get people buying things like these chapters/extras, get people happy by inclusion not exclusion.
