Pretty sure you cant grant levels to toons that are higher level than you. So the first post where he wants to stop at 40 and grant 20 levels to his other toon to 60 wont work. You can only grant levels to toons that are of lower level.

Im not sure why you would want to try and cascade level grants this way as it just goes to lower and lower leveled toons.

Your better off just RAFing up 2 groups of 60 and level grant a 3rd or RAF up 2 groups of 60 and 2 groups of 30 and level grant the rest for 4 full groups.
