Most people don't object to Warp 10 being the hard limit. Most people object to Warp 10 making you be everywhere at once. And the lizard thing.
I never saw the problem with the Warp 10 being everywhere. I mean, if you are travelling at infinite speed, then it will take you literally zero time to go from here to there. And if you are here and then there zero time later, then you are there at the same time you are here. You're in two places at once. And if it works for two places, why not three, or four, or ALL the places?
Mutant salamanders though, that was crap.
