So... the minions

Is there a set number in attrition? Are both teams supposed to get the same number?

Maybe my imagination but I notice when my team is winning by a decent margin the other team seems to run into a bargain bin sale on reapers. Its ridiculous, wave after wave keep sprouting as soon as they are wiped out. I realize killing them gives my team points towards a victory -- it's not an issue of fairness -- it's an issue of fun. I much rather be killing titans than be ass-deep in AI reapers.

Is it just that my team's reapers aren't finding their way to the action? Or are the numbers unbalanced?

I swear there are also always a ton of reapers from the losing team that materialize near the evac ship making it that much harder to destroy.
