Currently the winning team in ONS is either...
A. the one that destroys the enemy's base
B. the team with the most nodes at the end of the gather
The latter seems a little 'bleh' in the situation where one team holds almost all nodes for almost the entire gather, then gets pushed back in the last minute or so.
I realize that adjusting that would require either a domination or a TTW-style 'tickets' system - but then we do already, mostly, have the code for that, OR the bot could make that determination based on node statistics

This isn't necessarily a suggestion to make it so - but I do wonder what other players think.
