Perhaps it was just my absence from the game until recently(and I'd like to believe that as HTC seems to have its hands full already) but I can't help but feel the M8 has become a lot more sluggish with its speed, particularly from about 30mph+ the acceleration seems way off from what it used to be. Climbing hills seems to have become a near impossible task for the M8 as well and I almost always have to down-shift to 1st just to keep it moving on even some of the least intimidating slopes.
I can get a film of this tomorrow easy and if anyone else has noticed it that'd be great so I know it's not just me lol.
