Back then I played Warcraft 3 ladder games and I hit my skill ceiling quite fast because my micro was simply too bad/slow. I still very much enjoy real time strategy games. Is there any real time strategy game that is played competitively with an active community where micro is not that essential? (Ruling out Star Craft 2.) Besides real time strategy games, what other games are out there being played competitive with an active community and where clicks-per-second are not too important?
Probably not entirely your wheelhouse but have you considered coop turned based strategy games (or just turn based in general)? Something like Divinity 2 requires strategy and planning, especially on higher difficulties, but they are entirely turn based and can be played in real time in co-op. Alternatively, games like Disciples Liberation which centers around tactocul turn based combat can be absolutely brutal on high difficulty.
