Starcraft 1 wasn't all to perfect either =/
Dragoon ai was all around the silliest ai by walking into spider mines when you A-move and sometimes even glitch out and its still not fixed (probably because progamers can spend their 400 apm to micro them correctly). I still do the old 2-fact terran push and most protoss players can't control their dragoons properly due to minor latency issues and wobbly ai which always end up in blue goo.
