Different ppl have different take. It is not correct to say scout isnt the way to go or training a nordgen isnt the best way.

For me, the right scout will be with you until they retire. So 50 tokens doesn't seem too dodgy at all. As opposed to Power training a nordgen or Academy player - you need abt 300-400 green packs which, if you don't collect, you more or less would spend tokens to get them (could be >50T).

I've had a few scouts who stayed with me for 10 seasons and was top assists providers & goalscorers.

There is no right way to pick a scout but personally I prefer to go with dual role players unless they are MC or ST.
