Today I uninstalled halo 5 due to it game errors. I have had it happening to me too many times, where the game has given me losses because of the game itself. It becomes Boring and feels like I’m running around in circles.
It said 600 seconds to spawn in to the game on round 5 when you have 300 seconds to finish the round. And all the other game flaws.
Can’t be bothered to play this broken game, that has been broken like this since launch, and now we are talking about halo infinite. I as a customer is consantly getting consequences due the game’s condition. Had more than enough. 343 you are never looking into anything that matters, just listening to people that are bad at your games. Had enough
Sorry you had such a poor experience with H5, the game certainly has its flaws and many of the bugs/glitches are part of the problem. For me the most frustrating is being forced to wait for a vehicle bay that never opens; WZFF is a bit grindy in general and at this point is mostly for 152 hunters.
There are many other playlists however, and in my experience the balance, pace and challenge are all pretty good for halo standards in H5. I have been absolutely loving Mythic Slayer now that the ranks are fixed and breaks from the WZ playlist are pretty important to making the game feel fresh and not like you are just running around in circles as you describe.
Either way if H5 isnt your cup of tea I respect that, as its certainly a common opinion for the fanbase and its definitely my least favorite halo as well, but if you get a chance to take a break and come back be sure to try some Arena! The games unpopularity is part of the reason that I am actually glad focus is shifting to infinite; probably much easier to make the next chapter of chief epic and functional at launch then retroactively fix all the past mistakes. I hope you give the series another chance so we can join the fun on the next title 
BEst of luck in future endeavors
