Yeah you’re right. Why are mounts, pets, or anything giftable? Just don’t be poor lol.
Well if said person gets to 4k qp and doesn’t spend it on 2 costume gifts and/or the monthly costume instead of 20 boosters.
Well yeah that’s the point of boosters. Grinders can save up multiple boosters to do longer and more rewarding grind sessions.
Overall, I don’t really know how to sum this up so thanks for reading and Happy Hiving! 
Any available giftable item is cosmetic stuff. But talking about XP boosts, they aren’t cosmetic. They offer a way to boost the amount of XP you get per game.
That’s a fair point, sure I’ll give you that one. It is up to the person on what they can get.
Again, yes I do agree with you. No way I can defend against this.
Wait this is all true? Oh my non-existent god. I can’t believe this. How could this be possible? I’m just in pure shock from this statement.
