I have no problem with a hoarder buying players like these, after all if you spent so much time accumulating money you should be at least entitled to. What I have a problem with is a hoarder stacking 8 players like this into his/her team which will be beyond the club's economic means for a couple of seasons before selling them off. With a salary of 300K each and a salary cap, you can only stack a couple of them while still maintaining tactical flexibility.
you could build those easily with 30k players, too with the different that all skills are weeker^^
And those players aren't cheap, and you have problems to build then yourself, without sacrifying your team for a long time which you try to avoid with your cap(and even then you just got a few of them), but the people will know that those players are superior and are willing to pay astronous sums for them and the team who get the money to buy 5-8 of them will dominate normal teams with ptb and man to man.
The difference betwenn the world without salary cap would be, that with salary cap you spend your money at the beginning, without you will spend your on the salary updates.
