There are some microtransactions I wouldn't care about in CoD. Camo packs, reticules? Yeah, sounds good. New emblem parts? Alright, have at it.
Experience boosts, though?
Actually, sure. Leveling up faster isn't that big of a deal. Those who just want to get to max level and have all the options available can do that quickly, while those who enjoy the process of leveling up can go at the normal pace. As long as they don't make standard leveling take longer and the experience boost just puts it at a normal speed, because that would be really underhanded.
