343i has not been improving things for the Customs/Forge Communities. They've been progressively getting worse at each new game's launch. I have been fairly positive, apart from a few disgruntled tweets or posts when something particularly frustrates me, I've been sticking with "Yeah, I didn't like that either," because I hate being the negative douche that I know I can be.

Halo 4 didn't have a Fileshare or browser for a few months after launch. It also removed a large number of gametypes, like Assault, which severely impacted the communities ability to create and share content. They didn't release Forge Island until April 2013(IIRC,) and the three Forge maps that shipped with the game were a fraction of the Forge space provided in Halo Reach.

The Master Chief Collection hasn't worked properly since day one. I understand that. I get that they're working on it and I appreciate the effort put forth by 343i to fix their game and make it stable for everyone.

Matchmaking is working now and they're finally starting to turn to fixing the issues with Custom Games and Forge. For that, I am thankful. The File Limit is ridiculous and the only thing that I can think would explain that is what Spider said about compatibility with Halo 3, etc. and their in-engine limitations.

@Munky: I should stop being negative? Maybe the pot should stop calling the kettle black...
