Meanwhile, they still do some things worse than Bungie did. For example, their art design leaves much to be desired, and I think both Sabre and Blur have a better understanding of classical Halo aesthetics than 343i does. Also, Warzone and the REQ system, while great in concept, often feel more like a microtransaction delivery/revenue-generating system rather than a gametype and customization system optimized for fun and enjoyment.

Some things are just... different, and not necessarily better or worse. When it comes to gameplay, Halo 4 & 5 had gameplay changes that bugged me a lot. Halo 4's random ordnance drops and rank-based leveling system were terrible, and Halo 5 is simply too fast-paced for and out-of-place in the series, and 343i let pro gamers have way too much input, plus 343i seems to never want to have all gametypes present in a Halo game at launch (Halo 5 is still missing Oddball, KotH, and Race 10 months after launch). However, Halo 2, 3, and Reach also had various issues with their gameplay as well. Halo 2 had awful balancing in MP, plus the original Xbox version was plague with bugs and cheating, Halo 3's weapons were mushy-feeling and inconsistent because of reduced aim assist combined with removal of hitscan, and Reach's armor abilities were not very well-executed.

As for non-gameplay things, the Staten-penned Halo games (CE, Halo 2, and ODST) had really good stories, but Halo 3's was kinda meh and Reach was a canon-wrecking mess. 343i's stories are decent enough, but at the same time they decided to completely ignore all previous canon that all but stated that humans and Forerunners are the same species. 343i writers also write the games as if they expect the players to have read all the novels and comics (Halo 4 was worse about this than Halo 5). 343i and Bungie were both mixed bags in regards to storytelling, but in distinctly different ways.

I still think Halo might have been better off had Bungie stayed with MS and kept working on Halo simply because maintaining the status quo would have likely meant fewer radical changes in game design philosophy, art design, music, and storytelling, but at the same time I think 343i, with the proper shifts in focus and strategy, can better live up to the legacy Bungie left them.
