Its a little far fetched but listen to this:
What if we made the training really slow but then also put the emphasis on TPs
Like you start with 1 pl and 1 ki and so on. Every level you gain one or two on each stat depending on race and two tps with will add one point each to a stat or your choice. Then we could lower trans req and as you reach certain pinnacles in level you gain more TPs per level. Like say for sayians ssj could be at 15pl, but with an adjusted time frame so we can filter out noobs and keep the legitimate players. Three to four minutes to level up each time and every ten levels time for each level up is increased by a minute.
