Yeah. Instead of more health (c'mon, even on Easy the health levels for all units are unrealistic) they should just make them better strategizers. Instead of seeing 2 Scarabs and mixed units with enough health to withstand the bombs dropped on Hiroshima and Nagasaki combined, you could see a fully-upgraded Prophet, one Scarab, and 30 fully upgraded Engineers. Or even 2 Scarabs and 10 Engineers instead.
Instead of seeing a battalion of Wraiths and some other random infantry mixed in, you could see jumppack Brutes fly over a wall and own your base.
You could even just make those adjustments and test them before releasing a patch/entirely new difficulty settings that could be seperate from the current ones so we can choose either classic difficulty or new difficulty.
