I'll start us off with my opinions:
Queen Animation: I think the animation time could be reduced when queens lay creep tumors. I also think the creep tumor itself take just a tad bit long to finish.
Bunker Salvage: Maybe this isn't a small change, but I think an scv should be present in order to salvage a bunker--how else would you return the salvage materials back home?
Ultra vs ghosts: IMO, Ultras, especially with the armor upgrade should be immune to the ghost snipe ability.
Those are my 3 "little" changes. What are yours?
