I guess that makes me a unicorn ;-)which means you're the latest person on the internet to claim to be that elusive unicorn, the ninja ground master who trains on his feet, but knows the ground well enough to not want to be there.
Seriously ’though there are clearly limitations to ground fighting - these are generally overstated by folk who don’t train BJJ
There are also clearly limitations from rolling under a rule set - these are generally underestimated by folk who only train combat sports
Pretty much sums up most of these kind of conversations I think
