I like the idea of being able to get the desired hidden power on one of your legendaries, as mentioned there are a lot of legendaries that benefit from it and it contributes to improving the PvP aspect of the game with those Pokemons running around. The mentioned idea of lowering a stat to get the Hidden Power is also not bad, seems balanced, could be done with a ticket. There should be lots of thinking of a balanced way to get hold of one of those tickets though, because at the moment I don't know any.
I see a lot of people saying stuff like 'no a mmo is supposed to be hard' (meanwhile they all use BMS ofc) what doesn't really make sense, there should still be some hard way to achieve one of those tickets and working towards a desired hidden power on one of your legendaries can just be a great end-game goal.
Hope a staff member notices and makes work of it.
