What are the benefits of building two Infinity Edges?
So I just finished watching TSM vs C9 (don't worry, there are no spoilers in here :P) and noticed that C9 Balls had built two IEs... Can anyone explain why he did this? He built two on Gangplank and wasn't sure why he did it. Is it because there are only a few viable damage and crit items for GP? I know it's normal to build one on GP, but was confused when he bought two. Last time I checked, the bonus crit damage was a unique passive?
If anyone knows please explain it to me! Thanks
which has the same stats + cdr
