I feel like this series is one of the more evenly-matched games of the four. Both TES and 17G have looked to be quite decently sound teams, with the abiliity to clean out maps pretty well. 17G played amazingly against KBG and ODG, only falling short to DRG after winning 13-9 on Split. TES on the other hand, dominated TEC on all their maps but Bind, which we might see 17G pick if given the chance. 17G have a really solid Bind game but considering the fact that TES is first seed, they might just straight out ban it immediately.
I'm expecting a close match, but I think 2-1 TES win is reasonable.
