I would see:
1 - Same gameplay (some balance units and builds are needed)
2 - UI interface - more social interation, keep in mind the chat into the game is too old. messenger must show in the center (like blizzard chat)
3 - Entire compatibility (moderns system - alt tab), pause and unpause gaming.
4 - Support community with new revamp balance and keeping game alive. (like starcraft 2 and other MOBA games)
