LCS Suggestion - Tri Casting for Weekly Big Matches

Each week there might be a game or two that features two top teams, e.g. C9 vs Tsm or UoL vs Alliance. Those matches tend to draw more viewers so it is not a bad idea to get an extra caster in there to make the casting quality higher. It is not that two people casting is bad, its that when you have three people it's better, you get smarter and funnier comment thrown in there. Having a pro like Saint works so well because he has the game knowledge superior to any casters and he can make pretty funny remarks. Polly, monte are a couple other guest casters that may work well, on top of my head. I have complained about tri casting before in S3 Worlds Final but so far in S4 Worlds and IEM its showing the strength of tri casting (is that how you even call it?).
