Whelp, I tried to delay as long as possible for prediction, as there is seriously only one match currently. This match isn't very good to bet on either.. Anyways...

Fnatic > ESC! This is a Best of Five, and both teams will strive for victory here (Fnatic always does). Fnatic is currently performing on a higher level, a much MUCH HIGHER level than ESC in my opinion. Even if Fnatic aren't performing to their standard performance, they WILL win. Feel free to go high I guess, as I simply do not see any chance of ESC! winning (maybe a very very VERY slight chance, possibly revolving around using hacks)
I'm somewhat skeptical of matches with these insane odds, because if you were that team with the 95% what would you do given that scenario...? I'm sure over 60% would "throw" the match to get around $30 000+ total from simply one match!!! (Even though Fnatic are playing for I believe $1000 or so... $30 000 > 1 000)
My advice is to hold out from betting as long as possible, as there is a slight chance there'll be other matches to bet on. Feel free to place an EXTREEEME bet on Fnatic, if you dare, but my advice is to SKIIIIIIIIIP
