You realize Terran is garbage, being completely unbalanced with no overkill siege tank splash damage. All player communities are aware of this, and of the top ranked players, over 40% are terran. And Blizzard has refused to fix it since the second release of beta, showing their lack of interest in fixing the game when it doesn't directly increase their profits. And no chat channels. And the half the maps are incredibly small garbage rush fests, and blizzard refuses to fix that, too. And the achievements are broken. I forgot to say garbage in that last sentence. Garbage.
All games are garbage XD. Not really.
Well, it's a different animal on that side though, because MP is balanced insofar as it's actually possible to have a reasonable chance of player skill determining outcome in MP (the prime anti-draw in say random game spy games). However, they announced they're restoring chat rooms.
People always claimed imba in RTS. It goes back to even warcraft 1 and before! I've watched some elite games between races as well as played games between races myself. IMO it's far from determined that terran (or any other race) carries a material advantage in the matchups. I watched a pro match between zerg/terran the other day, and the terran did not win that game. People complained about night elf and orc heavily in WC3 too...I'm not sure the statistical outcomes supported those positions either. You say that 40% of top players are terran, but mind you that 1) the game is very young and 2) terran is the only race with which people have had extensive campaign experience.
If terran is winning a disproportionate amount of games, my bet is on balance changes. Unlike fireaxis/2k, Blizzard actually has a history of making balance changes without a whole new expansion. The best we've had from fireaxis/2k over the past 3 patches is the introduction of multiple bugs and a quad galley spawn rate (which is hard to argue was good for the game, given BTS moving triremes to MC).
Back to the point - THIS map. You will never, ever see THIS in any game that has a pretense of balance. You put this on deity, and you can't win at all. 0 chance from turn 0 short of cheating, incredible abuse of "features" like the AP, or a heaping helping of luck. Fun! But even on immortal, I doubt elite players will win their first attempt without considerable amounts of luck. If you know the map ahead of time, one can do some interesting type super chokes/etc, but that's it.
No matter how much you claim other games are garbage also, in a given game the outcome *is* reasonably determined by player skill and it *is* possible to win, at least for GOOD games. Civ IV is the best game I've ever seen that somehow still botches balance to hell and has controls that don't function properly. To its credit, that the depth it carries overwhelms some of the most basic and textbook horrible game flaws is impressive, and the fan base is rabid. However, none of that gives them a pass for this kind of trash IMO. Nobody playing on a difficulty they can ordinarily win will survive starts like this...it's completely broken.
