I only have one problem with how SKT v ROX worked out
I mean, first congrats to SKT for winning. I don't really care all that much about the result (as much as a SKT v SSG final would guarantee a repeat champion). There were some great games in there too.
My problem is that ROX brought out an unexpected surprise pick, support MF, and rather than a world class team figuring out a way to deal with and beat the pick, they were simply able to just ban it. Meanwhile players keep asking for more bans.
There was never an attempt to pick MF (and get a chance to see what ROX would to against it). There was never an attempt to change their playstyle to beat MF support (in game 3 SKT went straight back to Zyra support and basically tried the same strategy thinking they could win now that MF wasn't a surprise pick and lost again). They didn't actually solve how to beat the pick, they just dropped one of the power-bans and banned the pick instead.
It bothers me that the best players in the world have such an easy out. I understand that we also don't want a team to win the world championships simply by cheesing a superior opponent. I understand that the unique pick earned ROX two wins, meaning they only had to win a single of the other three games to acquire a finals berth. I'm just disappointed that SKT, likely the best team in the world, was able to eliminate a winning strategy with a simple ban. We never got to see a pro team beat MF support. Had it gone down as ROX taking MF support in game 1, then SKT trying to replicate in game 2 and ROX showing us how to beat it (then SKT winning the next 3 because they know how to beat it now) then great.
So we see all these posts on the boards about "X is OP" and the response is "X isn't OP just counterpick Y" or "just play differently against X" and yet the pro players see a pick that was nowhere close to contested, so far from it in fact that the referees had to check that there wasn't some mistake/bug when MF was locked in for game 2, and rather than apply the simple things that people use on the boards to mass downvote posts SKT just "bans X". Is MF support OP? Far from it. There are legions of strategies that wipe the floor with MF support - Zyra just isn't one of them. If anything I felt like Ashe won games 2 and 3, not MF. Ashe lost game 4 because she didn't hit arrows at all like she was hitting in games 2 and 3. I don't think an MF support would have helped them in game 4 tbh, but we didn't get to see it.
I felt the same way when Aurelion Sol was banned against CLG, but much less so because he was already considered a power pick / contested pick and was used by other teams as well. A ban on Sol did not look like an unusual ban. There were other examples as well. I don't think it really makes sense that a pro player can practice a non-meta non-OP pick and bring it out and win with it, only to have it mean nothing more than that - a win where the rest of the series is decided without that strategy in play because of a simple ban.
And players keep asking for more bans. This semifinal showed pretty clearly, there really aren't grossly OP picks in league. Sure, there are annoying picks and lane counters, etc... but when a pro team can sacrifice a ban on a champion that wasn't even expected to show up in that role at any level of play it shows that power picks really aren't a huge deal. Counterplay or solving how to beat a pick isn't a required skill either. All you need to do is ban the pick, and be able to win 3-0 when the strategy isn't active. Which obviously is still hard and shows why SKT is such a great team - but still I would have become an SKT fan if they let MF through again and showed they could adapt and beat it. They didn't - so frankly I'm a ROX fan after that match for being able to pull out the unexpected and make it almost carry them to the finals.
