I should have done this weeks ago, I thought I could do "last balancing" to get a better foundation before pushing to "Live / Production". But next step was to rework the map & updated units, that would mean I would have to balance the game again afterwards, which felt it wouldn't be well organised development time (e.g. "waste" of time to balance units that are going to get new behaviour).
And the experimental-version has a better version than live (The nasty lag-fest in the end), so no reason to keep live in worse state.
