which slows down gameplay considerably.
It would be fine if all of these things were in the game and you were able to turn them off, however the maps are designed to be played with such things making it impossible to play at a faster pace without them at this point.
Look at Reach and H4, all of the maps are vertically based in some way because the jetpack was in the game. H5's maps look to be pretty good and the sprinting mechanic does seem more balanced, but all of those abilties are not needed. It would be fine if just sprint was there, but it isn't and thats the main problem as to why Halo games have been failing.
You say we can't have the same game over and over, but yet H1,2, and 3 were all essentially the same engine with slight tweaks and improvements. Reach added so much to the game that it broke how it played.
