Your reasons for unsubbing are entirely yours. If it stops being worth it, or youre burned out, or its just not fun anymore and you'd rather do something else... its perfectly valid. You dont need to engage with anyone telling you you suck or you cant hack it or youre looking for free handouts. If it no longer feels worth your time or money, because of your goals, your time to invest in the game, the competition, your temperament or whatever else, your reasons are yours and they are completely justifiable based on those reasons.
And if you love the game, love the changes, love that you can quickly get to the content you want to play, and love playing that content and love you can keep playing it, youre also valid.
And by valid, i mean absolutely correct in your decision. This is the hippy thread where we all just stop trying to convince everyone else that theyre wrong.
