What stats are you looking at? They must look very different than the worlds stats I've seen. Especially if you think that removing SKT would make the REGION of KR less of an impact. Let's break it down by region so you can see what I mean based on stats and if you don't get what I mean then you can say something (although if you don't get what I mean after I break it down it's probably me trying to discuss something that is your ideology rather than an opinion and you won't change your mind no matter what logic is used bc it's an emotional argument rather than logical one for you).
For all of this we will break it down after season 1, bc season 1 was just NA and EU really.
We'll start w/ KR given that saying KR isn't the most dominant region hands down w/out SKT is the easiest assertion to prove blatantly wrong:
Season 2: Both groups are won by KR teams and both KR teams are beaten by the winner (TPA) with Azubu losing in the finals
Season 3: Top 2 KR teams meet in the semi finals and go to 5 games, while CN and EU (Fnatic) meet in the other semi and go to 5 games. SKT wins the finals 3-0, and so if we remove SKT there is still Najin in the finals and they most likely still win.
Season 4: SKT doesn't make it to worlds, all 3 KR teams still take 1st in their group. Najin is beaten in the quarters, but SSW and SSB stomp NA teams and basically play the "finals" match when they meet in the semi finals.
Season 5: KR is the only region w/ multiple first seeds in the bracket stage, KT is one of if not the favorite team to win the tournament should SKT not be there.
KR still has a Championship (probably 2 if S3 was played out) even w/out SKT and is in every single finals match for the last 3 seasons (and let's be honest, this one too). Samsung and Najin organizations have both sent multiple teams to worlds and would likely each have a title if not for SKT. No other region can boast a strong chance to win worlds w/out their best team from the region. KR can.....
Next we'll do LMS:
Season 2: TPA won as huge underdogs
Season 3: all their teams were stomped
Season 4: Still bad, although AHQ might have made it out of groups if they had been lucky enough to be in group B instead of TPA.
Season 5: Both teams cleared groups (only region other than KR w/ no teams eliminated during group stage, but only had 2 teams and FW had easy group), but aren't likely to make it to semis
Not a strong region, and while it looks much different w/out the championship from TPA, AHQ has looked strong this season and last compared to many EU/NA teams. This region does fit the category of "if you remove" though bc they have a title in a season where CN and KR teams actually competed (Season 1 was NA vs EU and EU developed the meta we have followed since then so they crushed NA). If you remove TPA this region loses relevance.
Now CN:
Season 2: Lost in quarters, still a weak region and was dominated by EU (season 2 is the best case for EU region strength)
Season 3: CN develops as a region an OMG dominates groups going 7-1 to match SKT in their group. Unfortunately OMG is paired vs SHRC in the quarters and loses. IF OMG had drawn C9 or Bears they would have made semi finals most likely so my guess is CN has 2 of the top 5 teams at season 3 worlds.
Season 4: 3 CN teams instead of 2 this year, they win one group and place second in 2 behind the two SS teams. CN plays one side of semis while KR plays the other. Of note is that SHRC is the CN team in the finals for a second season.
Season 5: Teams implode at worlds and only EDG makes it out. EDG vs FNC looks to be a good quarters match up, but LGD and IG didn't show up until week 2.
You could argue that if you remove SHRC CN is less relevant bc that is the team that went to finals 2 times. You'd be wrong though. OMG matched SKT through groups and would have stood a good chance vs FNC if they played in the semis instead of SHRC (more of a toss up though, but since SHRC won 3-1 there would be a chance), and EDG vs OMG would have been the semis last year w/out SHRC so CN would still be finals then too. Additionally SHRC isn't around this season, but EDG has shown up big, so you can't argue that removing SHRC makes CN less of a strong region bc EDG and OMG back the roster up.
Now NA:
Season 2: Not relevant (although CLG does own CLG.EU and there was the whole dig strat accidentally leaked this season if I remember right, so NA is at least relevant in names and controversy)
Season 3: C9 beats maybe Bears and Gambit, but is generally not relevant here either.
Season 4: FNC and LMQ probably both could have cleared the SHRC group easily if they had the TSM/SK group draw, but get knocked out in groups vs 2 semis teams (ssb and omg). TSM/C9 get stomped in quarters. C9 maybe could have beaten Najin/edg/omg if they had a good match, but most likely loses their quarter no matter the draw, and tsm definitely does. Still fairly lack luster w/ only C9 really mattering.
Season 5: All eliminated, been a weak region all season.
W/out C9 NA loses any relevance they have
Now EU:
Season 1: FNatic take title, although really just vs NA, it's still cool.
Season 2: CLG.EU and M5 make semis. M5 looked really good, but was very different to EU teams and I did mention them earlier.
Season 3: Fnatic makes Semi's, could put up a match vs a number of teams, but gmb loses to anyone except the bears imo if I remember how sloppy the games looked (been a while so maybe I'm wrong)
Season 4: No team clears groups (FNC had a hard one, might have cleared in B or D)
Season 5: FNC 1st in groups, OG 2nd
Other than s2 Fnatic is the only one in semis, but honestly given S2 you could argue that removing FNC isn't as big a deal to EU as removing C9 is to NA. However, I'd still argue that M5 wasn't really hyped as an EU team but rather "the russians" during season 2 and played a very different style so if you categorize them as their own thing in season 2 then what I said would hold true. It is true though looking at the data that I over estimated Fnatic's impact (they didn't even have a better record than LMQ in groups last year, and they didn't show up in S2 at all), and under estimated M5 and their connection to EU (transition to GMB and still show up for worlds as an EU team).
So yeah, I was a bit wrong about EU and Fnatic, but other than them there hasn't been a team that comes close from the west to matching CN/KR dominance, and even if you remove the top team from CN/KR they still put someone if not 2 teams in the semis and the final. Out side of the M5 run in season 2, no team has looked as close to competing w/ the east as FNC has, so I don't get why there is all this NA vs EU rivalry. It's like arguing over JV teams while Varsity is gonna play the same tournament and everyone knows it.
