I don't think Dardoch can work out for any team. He seems to have the same problem Piglet did which makes the fact they put Fabby in to replace Piglet to appease Dardoch that more confusing. Plus after finishing worst i can't expect much out of Echo Fox.
As for TSM I like their chances of making it out groups, but I still feel NA/EU are easily the two weakest of the four main regions although moving to Bo3 should help TSM/other NA teams compete better.
For worlds I think: All 3 LCK teams make it through, assuming KT wins the gauntlet.
China has 1-2 teams make it through groups.
One from AHQ's region.
1 from Europe (G2)
1-2 from NA (TSM and likely C9, if C9 lose gauntlet then likely only TSM)
I could see TSm and/or G2 making it past the first stage of playoffs there depending on who they get put against. Just like last year and Fnatic/Origen. Still think ROX/SKT win at finals which is really all that matters.
