Added the eponymous watercourse at A and blue spawn area.
Edited blue spawn area so the watercourse could flow through it more naturally.
Made left flank at A more interesting.
Removed a bridge at B forward hold, as it was giving blue too much advantage over red's hold position.
Change the right flank at B to connect up with the lower control point room instead of the right side high ground. This is an experiment to improve gameplay flow.
Changed some health packs.
Adjusted respawn timers.
Other minor changes.
