TSM can only improve off last split, and they finished second. Now with a new support that will synergize with double and double can also help guide him in his roll for the team. One of the best things about LCS rookies is it seems they can be molded pretty well by the team into what they need.
IMT was a monster last split, there is not much to be said here. Huni is a beast most the time reighnover is super solid, Turtle and adrian are aggressive early and it works with the ap supports of adrian letting them snowball the lane. then pobelter is a solid mid laner who can fill the roll of what his team needs at any point in time.
CLG have proven to be a strong team, their play is focused on synergy and they have that in spades. They lack mechanics to make out plays in mid and in adc, (ooo gana piss people off with that, we will get back to this later) the thing is their mid makes a lot of mistakes and usually the team is able to bury it in overall teamwork, however there are times were they can't. Then with the ADC his mechanics are overall pretty decent his positioning is amazing but he is never one to make a flashy play, he plays safe stays in the back line making sure to not overextend but always there to clean up, for a comparison he plays more the style of Sneaky then Doublelift. With that all said the other teams have better mechanics and the ability to outplay them in team fights, for example the fight breakdown by TSM Jatt this week were CLG lost a 5v4 against SKT. Where their edge is, is macro play and I don't think that will get them threw IMT or TSM.
Cloud9 with massive changes to their roster they upgraded top lane but added a language barrier, they changed their support to bunny a better support in lane but the loss of Hai as a team captain. The change to meteos is an unknown yet on how he will perform having been out of the scene for so long. Sneaky is Sneaky so there is that. Overall they rebuilt their team and in the long run it's probably for the best but they will struggle early.
TL finished 4th and have made no changes to the team. They have great synergy with the team but they need to work on their macro play. piglet and dardoc have amazing mechanics but without better overall macro play of the map they will struggle against these juggernaut teams competing for 1-4
That's about all I want to get into it. Echo might to better then I gave them credit for, they started to pop off at the end of last season.
