I'm a long-time RTS player (DoW1&2, WC3, SC:BW, SC2) and overall, I really enjoyed the beta so far and I pre-ordered the game today.
I have one concern though that might partially solve quite a few of the issues I've heard people talking about the game (in terms of lack of strategic depth and macro).
IMHO, the map we played on for 1v1 is simply too small. I've seen the same problem of small maps in SC2 during the long beta and even more than a year after release (where I was a Top-200 Player in EU). The Maps were so small, that many strategies were simply 1-base and rush-oriented and people blamed game-balance and other things for it. As soon as (which took a very very long time) blizzard recognized that they have to implement maps made by other people into the ladder, the game got a lot better and more strategic and macro-oriented.
I just wanted to discuss this topic here a bit: How many Maps are planned for 1v1 at launch, how big are they, will there be a map-editor, are there plans to regularly implement new maps into the ladder, will you maybe host map-making contests to implement the best community-maps into future ladder-seasons etc.?
I just come from games where maps have been a huge issue (for better or for worse) and I can't stress the importance of well-made maps enough: SC:BW is pretty much balanced via maps and there is a professional map-making community driving the whole thing. SC2 was horrible in terms of maps, but got a lot better once Blizzard realized they need to keep up with the cummunity-made maps. WC3 is probably the worst example, where the same maps have been played for years and years with only very few additions in recent history.
