Could it be possible to train abilities only 1% at a time, maybe with some
penalty? Penalty could be like 50% more cost compared to 5% blocks, or
possibly losing 20% of the trained exp permanently. Functionalities wouldn\'t
have to be changed, they could do nothing until 5% is trained, just like some
abilities need 100% until they work.
The numbers mentioned are of course only suggestions, point is that this could
be implemented in some way which isn\'t very suffeli.
