Well Guild Wars 2 mincrotransactions aren't that bad. You don't but items just the ability to change your character's looks, dyes which can be found in game, exp and other boosters which can be found in game, keys to black lion chests (think crates from TF2 but better since they give you more than one item) that can be found in game, and weapon and armor skins. So basically GW2 did it right because almost everything you can buy you can find in game.

And even thought you can trade the gems (the currency you buy for the microtransactions) for gold since the end game stuff cost over 1000 gold if you buy them through trading it dosen't hurt the balance of the game.
