What is one of the biggest complaints of level sync? Losing all the skills. It might be too much work. It seems like everything is too much work. But moving a lot of skills down to lvl 1-10 and have the new skills evolve from those. They already have the animations partly done. They can balance the skills to that level. People who are synced still feel a similar game play. You start learning larger rotation earlier. They don't have to worry about skill bloat or balancing old skills since you won't be able to have them at the new level.
