Microtransactions are bad if it effects the success or failure of the gameplay. I don't want to have to pay for a weapon or armor to succeed in the game.

I think microtransactions are best for customization of our avatars. Purely cosmetic and things things that don't effect the success or failure of gameplay. Another words I'd pay if I could change my character's looks without effecting the statistical implications. Or buy a stylized weapon that had exact same stats as one that I own.

Soon as microtransactions effect the gameplay, then it comes down to who is most willing to spend money to succeed. Hardly a mark of a skilled player.
