XP boosting is a nonproblem.
Is it unfair? Yes. As is all cheating. That said, it's not actually the point; the point is that 343 (and all modern game companies) want folks coming back day after day, rather than simply coming in, hitting 50, and leaving. Can't forget to water your crops or your farm will shrivel. Be sure you Like us on Facebook.
Now, despite the fact that Halo 4 contains a significant amount of time-gated content (Spartan Ops most obviously, maps from DLC secondarily, Specializations being released a few at a time, daily/weekly/monthly achievements, etc.), 343 also considered it important to put in an XP cap. Not only to purportedly stop boosters (a nonproblem which XP caps do not solve), but also to make sure that people come back a little every day, rather than a lot all at once.
That'd be fine, except I work long hours, and my weekend days are the only days I really get to dig into Halo and enjoy myself.
This, coupled with the fact that there's a 2x XP promotion from Mountain Dew and a literal monetary reward (as MS Points) for playing a certain amount of Halo in the first month, means that I think the entire system was slapped together by a bunch of monkeys.
You are solving a problem that's not there. You are aggravating me, a perfectly legitimate player and until-the-cap perfectly happy customer, by punishing me because other people might cheat, or because other people might not play constantly.
It's kindergarten logic; uh oh, Johnny stole extra cookies so now no one gets cookies.
That is for children. I do not appreciate being treated like a child, or a cheater, or any combination of the pair. I'd much rather be treated like a customer who pays you folks for a service.
I don't play this game just to level. I just prefer to level when I play the game. I only play legitimately and I've run into the cap two out of my three weekend days. I will no doubt do the same tomorrow, and each time I curse whatever designer decided that something as simple and thoughtless as an XP cap would be a solution rather than an additional problem.
I have not had my gameplay experience degraded by XP boosters nearly as much as I have by your XP cap.
Please do something about this, folks.
