I would venture to say a good chunk of people expected for H2k to get out. Just because it's not a caster prediction doesn't make it wrong. Looking at their competition and their play style it all boiled down to H2k themselves, would they show up (to the fullest of their potential) or would they crumble. As we saw, they clearly showed what they are capable of.
Every region plays a little bit differently, but ultimately there's one end game goal: the nexus. Doesn't matter how you get there, you just need to get there. That's what makes worlds enjoyable, the differences in play.
"Don't expect what you think going to cus look at ANX and H2k"
This statement just makes me wonder if you have went the extra mile to even watch all the regular season games. Sure, ANX I'll give you that one, but every other team in worlds wouldn't give them a chance as a scrim partner expecting freelo, which in turn gave them a perfect disguise (for their play/picks (minus a few)). The teams that fell to ANX deserved it.
