In my opiion I think the 50 Cr Ready Go's are a wonderful idea.
You can relate the Ready Go's to Legend's and their abilities in a way. Some have been calling for Legends who have an average of 58 and lower to be in a tier of their own, which isn't a terrible idea. You could call them "Champions".
With the 50 Cr Ready Go's I know that I might stand a chance of winning at an affordable rate as I think the "Champions" would not play them, as they not profitable enough.
50 Cr Ready Go's really gives an opening to the average or up and coming Legend.
