Dyrus is not the problem, but the rest of TSM is.
Dyrus is not the problem. Yeah he gives up a lot of kills because he is super aggressive, but he is kind of forced to. He never gets any help from anyone else on the team, and because of this he has to do everything he can just to keep up. In all of the games I've seen TSM play the games that they won the easiest were games where Dyrus did not get shut down. Every other game Dyrus was getting camped and struggling in lane and even if TSM won they did not have an easy time doing so. This shows that when given the opportunity Dyrus can and will carry.
If TSM is not going to lane swap then it is a given that Santorin is going to have to help the bot lane. Wildturtle and especially Lustboy are great players, but they do not do well in a 2v2. I think this is where a lot of the mid lane and bot lane focus comes from. TSMs bot lane struggles in 2v2s so they need help with those, and if Bjergsen gets ahead he will carry. The rest of TSM is the problem. So what can TSM do to fix the problem with top lane?
First obviously with the way Dyrus plays he is going to be camped so why not instead of immediately going mid after a few camps Santorin go top to counter the early gank which would possibly help Dyrus get ahead. Until Dyrus gets behind the way he plays allows him to get ahead of the enemy top laner on his own. So by counter ganking the obvious gank early and getting Dyrus even further ahead (to a point where he is not in as much danger to giving up kills) he will be able to carry and win his lane on his own, and then Santorin (or Lustboy if he is roaming) can help elsewhere.
Second Bjergsen is best on play making champions (champions like Ahri, Zed, and LeBlanc). So why is he not playing thsese kinds of champions? Why is he playing champions like Cho (or at MSI ziggs) who need help to get ahead early? If TSM were to put Bjergsen on a champion that he can win lane on his own (or with minimal jungle intervention)and then go on to carry lategame he would not need the constant presence of Santorin to win. Even if he is going to be unable to get solo kills and dominate lane alone he has some of the cs scores of a mid laner at 10 minutes and often out farms the enemy mid laner (even on champions like Cho) so he keeps himself ahead and keeps pressure in the mid lane even when Santorin isn't there. I think that TSM should wait to help get Bjergsen super far ahead because he keeps himself ahead on his own, and instead focus at first on getting Dyrus and the bot lane ahead.
Third the bottom lane of TSM is not good in a 2v2. Overall this is not a huge problem because TSM plays lane swaps so well. But if the opposing team sees the lane swap coming and then match it then the bot lane remains in a 2v2. Still this is not a huge problem because there is a lot of ways to help them in a 2v2. Santorin can camp them and Dyrus has tp. Honestly the bot lane of TSM suffers when Dyrus is shut down because he really can't help them so if Santorin is off elsewhere and the gank comes in TSMs bot lane is screwed. Until Bjergsen gets ahead he really can't roam to help the bot lane which typically leaves Santorin and an underfed Dyrus as their only help.
Bjergsen has shown he does not need help to get ahead so instead of focusing his lane TSM should focus elsewhere. Dyrus has shown that when he gets ahead he can and will carry, so TSM needs to help him get ahead and prevent the obvious ganks (If they warded top at all it would be a miracle and Santorin might not need to help Dyrus). The bot lane struggles in 2v2s, but if Dyrus gets ahead he can help bot which would allow Santorin to help Bjergsen (if Bjergsen is not already ahead or in a position to help bot). TSM needs to put less focus on mid (Bjergsen will get ahead early on his own and can wait for the jungle pressure. He doesn't need immediate ganks) and they need to put more focus on top so Dyrus can help the rest of the team during laning phase and team fights.
