Hey, no need to sugarcoat your opinion like that... and what's wrong with melee maps now? The SC2 campaign was pretty good but I personally would've liked some basic SC1-style missions added in there, instead of all those "here's where you build Medivacs to pick up guys from rooftops" or "here's where you build Battlecruisers 'cos other units can't go in there". A lot of people probably prefer that but the missions just felt gimmicky to me.
I'm not gonna argue that the Jacobs mission is even close to optimal playability, but hey, at least it's not a melee map, right? The RTS mode could definitely be added as an option. Is the pure A-click/right-click gameplay that much more interesting, though?
EDIT: Ultraling beat me to it, but yeah. What he said.
EDIT 2: Oh yeah, about the talking portraits, it's made to be a stupidly time-consuming task in the Galaxy Editor, and finding the right animations is indeed a pain. The portraits would probably still occasionally stop talking mid-sentence, and it would look awkward.
