So after switching my team from Rex to Luke I did some fights. Starting of with one crit from Han, cool 7,5% TM for the enemy. The hole team goes before me and there 60 speed difference. After watching this a few fights I think there are some issues with the amount of tm they gain. If some more people can test this or a dev takes a look on this. So I can be sure there is no bug. If the lead is not bugged, I would say he needs a balance update.
