These are a few main reasons why I don't:
- The performance/smoothness/fps is not as good as 2.3.8 in Multiplayer
- Trap Cursor is broken.
- No more magical knowledge of the enemy's unit production (I think this could be "ok" if sensors had a much larger range (2x) but would need to test).
- No one else plays it.
Also (this is trivial), as a native speaker of English I think it'd be more sensible to call master releases snapshots. It just seems silly to me to keep referring to ever-changing builds as "master"
