imo the best reason to buy players at this moment is if ur in a crapy server as i am.
If u wait on sunday the token war is 100% sure.So u can find some good players now that u can keep them until the end of the season and sell in the middle the oldest ones.I did that this season when i realised that my server is so crapy that i had to spend 20-30 token to buy a nice player(and if i find it).It worked ok ,i already took my league,it cost me my CL although(while i was changing players my team was confused) and i hope i get the cup(i am in the final)
