That worked for me too I did not see anything weird happen but my age went up a bit. I liked reaching a level I want to be at rather than going back each time. Please add it to the other skill places.
JB said he was testing it first to make sure it was working properly before putting it in other places. There haven't been no complaints yet.
I also caught the new event that happens when you use charges.
I will add Forced Training elsewhere shortly but I doubt I will do the same with Jobs. Players need to feel the element of 'working' for their gold so it doesn't all feel so easy. In this way, gold is valued for what it does and isn't an instant problem solver for challenges.
I wonder if we can get a use manitou elixir in the options when out and about as when you are running low on MP it could come in handy to get some more MP to keep on going. Just like the use of healing potions.
