It's not 'cheating' but yes your right spending plenty of money on tokens does make things a lot easier but it doesn't guarantee you will win, I maybe should of kept it a "token free" squad on my team but I decided to buy around 3,000 tokens once and power trained my squad to see what its like to have that over powered team, yes I do agree token buyers should receive some sort of 'advantage' because they are spending money buy I do think that non-token buyers should be given a fair chance to win against such teams.
When you win with a team full of scouts from bought tokens you don't sense much in the way of achievements.
