i'm in the same boat as you since i have tate and am wondering if i want to trade for foster and i look at it like this: If foster plays, tate has still earned himself at least 10+ carries if foster is out then tate gets all the carries with ward being injured. Is it more risky to give up mendy for a timeshare or would you rather keep mendy with the hopes that foster is out and tate becomes the man. I can't give you a definitive answer since i can't even decide this for my self but those are the pros and cons that I am weighing.
since i mentioned it lol help? viewtopic.php?f=18&t=496021
