Changing the UI will not change the fact that well positioned Siege Tanks will still demolish anything else. Which is the reason for dropship play, which is pretty dynamic imo.
You should probably check out some of Leta's TvTs. Less passive TvT's involving wraiths and lots of harassment.
Also large maps are good for macro games, and longer games are more entertaining. If i was baller I'd show u a graph but im not so u can just pretend.
Should also check out some of Day9's BW dailies on TvT if you don't really "get" TvT.
EDIT: Also who the hell pans the camera? Like I only scroll a little bit, but its not noticable. It's not that hard to press f2/66/77/whatever.
