After the initial withdrawal of the patch, the whole month of April was available for balancing the v1.02 in addition to whatever time was available towards the end of the original 3 month patch period.
Balancing would take months in testing time. Yes the patch was originally meant to be out in Feb and its now May, but as it was a series of successive delays they could never commit to adding in unit balancing given the delay it would me.

I've also chatted to Palamedes about it, he even worked on balancing with me for LTC 2.3, so play that if you want to see what me and him came up with.
