Sorry, but I must at some point defend my opinion: why on earth are people in this forum always claiming that scouts are not effective ??
They bloody are!
I won 2 treebles in a row with a roster made of 90% scouts.
Ask my current opponents in CL or cup or league if they are not.
Explain to me how you are buying a 5 star, 18-year old youngster (without tokens for sure - not even token wars !!) and train him to the level of my 6 star scouts (getting close to 7) ? With on top, 2-3 positions and a SA ??
Scouts are sure deals. From time to time, you get a bad one but he will still contribute to the overall ranking of your side, which is something critical I think, as games are resolved by a computer program.
Training a player costs tokens ! Here in France its way easier to earn tokens than the green/reds packs you need to train your players. And the rate exchange is simple: 1 pack is worth 1 token or so.
When I buy a scout I get who I want, when I want without gambling on a potential token war that could leave me with nothing.
On top of that -believe it or not - I do not buy tokens. I'm earning them through (mainly) surveys.
It is time consuming but it works.
And yes, you can rapidly end up with hundreds of tokens if you play on a daily basis.
