There is an absolute deafening silence from Roll20 on this topic. The system has had a huge boost recently but there are other VTT's that have very good character sheet build tools. Maybe instead of refining the Charactermancer beta (which at this point really seems beyond their capabilities) perhaps an import tool from systems like Pathbuilder would be a better approach or a character builder AI so anyuone can integrate with it ? Something needs to be done, and done quickly, even if its just an acknowledgement that something is in the pipeline or FoundryVTT and others are going to see an exodus to tme much the same as Roll20's favourite child, D&D 5e, is seeing an exodus to Pathfinder
