Maybe for the following words it's important, to see my playstyle:

I kept exactly the same team over the last 3 seasons and won (without manipulating) all 3 seasons the triple. I build up a team and keep them as long as possible. I also have one player since season 2 (currently 11) - this one, Kraxner, is the last one, who isn't a (good) fast trainer.

This season, I need(ed) 2-3 new players, because my team gets old, some of them can't go on and doesn't perform. Kraxner is the weakest on stars/quality and he still performs well, BUT he also becomes old...

From beginning of the new season until now, the market was kind of bad, so I decided to give an academy-player the chance to show his skills. It was a ST (who I needed), 82% and cost 12 Token. I was lucky, it was nearly a perfect FT. He played 69min in 3 games and scored 4 times.
A friend also got a youth player, even with two positions. He was only 80% and cost 14 T. He isn't that good FT, but... he performs perfectly. Every match, he was rated 8 or higher, and today, at CL, vs a 7% stronger team, he made two goals/two assists (result was 4:0)

Maybe, we were really lucky to get this guys, but if this is the way, how academy-players go, I'm fine.

For my playstyle, I would like to see them like this:

-) very Fast Trainer
-) able to select, what you need next
-) maybe SA or 2.position

If they are like this, I'm ready to pay 14-20 T or more, because if you see biddingwars the first days, this is really fair... but to gamble, what you get... the price of 5-14 T is too high.
But I'm also one of the players, who would buy recommended players, if the are good (because the cost the bring up a 99% to 119% and give them 2. and 3. position and SA are a way more, than a "finished" player).
