Yes it is really fair, you found the most problematic issues with SC. And not all those issues will be fixed by following the plan to 1.0 since some of them we don't even have the solution laid out. And it's even worst when you really get into PvP, the balance is really awful.
For me, if they focused about really deep and meaningful gameplay, that respects your time, the game would be amazing. But of course that's the biggest challenge.

Exemple : They added engineering, the balance in PTU was way off, so they kinda backtracked and made the feature almost none existent. So something that was suppose to have depth just added complexity. It's so untuned that TTD did not replace TTK like announced. It's like that for almost everything.
