No, just no for most of these. There is nothing mechanically wrong with SCV's gameplay systems and it is the most balanced SC game. It's pure bias if someone thinks a previous SC was more balanced, including the best overall one, SCII. Remember to not let nostalgia cloud one's judgment.
SCIV was rubbish IMHO, and the Critical Finish system was awful. Creation & customization in FG's is a bit of a double-edged sword because, while I don't mind the feature, the vast majority of people who utilize it online either produce something that looks like shit, or are just recreating some pre-existing IP (I.e. the billion Cloud, Dante, and Sephiroth clones). However, I have seen some genuinely solid creations, especially some of the one's posted on 8WR.
By the way, the aspect that made SC so "memorable" was its offline offerings (such as those in SCII & SCIII), which were top-notch in the SC's prior to SCIV (I.e. before it added online play). If SCII had weak offline content, no one would praise it as highly as they do. On the other end of the spectrum, SCV does have a very solid online component to it despite being at the expense of an expansive single-player component. Although SCV was rushed, I feel that people come down too hard on it because they expected it to have the offline content of SCIII coupled with its solid online play. If SCII & SCIII had online modes, their single player content wouldn't have been nearly as solid as it was and vice-versa for SCV.
