What are some basic mistakes you still see players do (or you catch yourself doing) regularly that should never be done? I'm mainly starting this to identify and self-correct any bad habits I have. One I noticed I still do is move several tiles at a time. There's really no reason to do this, and it can put you in a bad spot if you stumble onto an enemy during the first step. I'm also overly tempted to build a scout first every time and I never fail to regret it when I do.
