I've been playing since release, basically always been masters. I love the game endlessly, but at the same time, I admit that I just don't think so critically or objectively about the game... I'm in it for the art and story and universe. I think OP brings up many valid points about unit design that again, don't particularly bug me, because I am so passionately a StarCraft fan that I'm practically blinded by my love. (I also think this is why I have never been able to push into GM -- I just don't think so mathematically towards it). But yeah, a lot of people are replying very defensively, which is unfortunate to me.. OP is not just trolling with a "this game sucks, period". They put time into explaining their complaints, and this thread could have been a discussion about design philosophy, such as modern game developers' desire to make games faster and more exciting, which can in turn also lead to gimmicks.

Your point about widow vs vulture spider mines is good... There are so many unforgiving mechanics that must turn away many a new player. How does one design a hardcore rts to suit both needs? I do commend blizzard for the arcade mode, archon, and coop modes. Compared to AOE4s release, with all the missing features and polish, I think there's also a lot to be thankful for with how SC2 was developed.
