that is my case too and had same QSs too
scouts problem is they are only good for one season or 2 at best .. unless you buy 2 green packs (extra 90 tokens - not even counting red ones , so real price is 100-150 tokens) top improve him which i find nonsense, as i can buy another scout and reinforce me team instead .
i tried to work on 18yo 4* with big potential (bcz that is my stupid server give me all the time), and spend 2 greens Packs, to make him scout .. that is coming back again with 100-150 T to make him scout .. when i can just buy 2 scouts for that price .. crazy
so both not working for me
but recently bought 3 18yo/19yo with 5* in mid season, i gone to round 20-25 but get them double the price but still worth every penny
they were 1-2 point short of scout, and what is good about them is they develop so fast and will keep developing fast over the years, unlike scouts players
so my advice is:
* buy 2-4 scouts max every season, as only way to boost their skills gain is by getting MOM rewards, so you shouldn't have alot of them, next season they will be 5* and enough for rotation
* buy as muchas you can 5* near scout , and pay high price for them, those are the best investment, as will take less packs to get into scout with no time, and will keep improving over 2-3 years unlike scouts
* buy talented potential 4* if you couldn't have alot 5*, just for rotation
* try to make your team as better or at least as good best side in CL and league, not worth investing more on greens when you it make more sense to buy younger players next season for same price and waste greens & tokens just to be so superior .. i hate be too superior than other teams , just slightly better is what i aim, as i want to win using my tactics , it is just more fun and thrilling this way for me
