Halo CE Vechles Nerfed

Has Anyone else noticed that all the vehicles in Halo CE are no where near the same with the weapons as they were in the original. the accuracy is non existent. While the original and 360 remastering were identical in gameplay the MCC edition has crapped itself in comparison.

343i is there a reason for Nerfing the vehicles?

Ok I think It may just be an error when game scoring is activated, restarted the lvl and everything seems to be in order
