Which teams do you want to see play eachother in the kickoff event? I will start.
Americas: any combination of nrg, sen, lev and loud.
Emea: navi vs vitality.
Pacific: prx vs drx.
China: dont know.
I think it'd be a fairly close game, I think people do forget how insanely talented this 100T core is in terms of raw mechanics because of how badly they threw away an entire season due to a lack in coaching staff and resultant lack of confidence. An in form Cryo + Bang paired with the in game leading, calling and energy of Boostio seems like a pretty daunting team to face, even for Sentinels.
Well, the main teams (with rosters atm) to watch during international league/event (if you don't want to watch the league) are:
EDG: Appeared at Champs '22, LOCK//IN, Masters Tokyo, and Champs '23. Goated team, probably will win the league and end up as first seed for all the international LANs.
Watch for: They were burned out and tired so unless they don't recover well, expect them to dominate China.
FPX: Appeared at LOCK//IN and Champs '23, but got eliminated immediately.
Watch for: They signed Autumn, a cracked Australian duelist who is imo highly underrated. Rest of the team has also made big improvements. They could probably challenge EDG in the league.
BLG: Appeared at Champs '23 and finished 7-8th
Watch for: They could be frauds, but on paper they are still one of the best Chinese teams. We might see them drop hard this year. Honestly, imo they probably won't challenge EDG in the league.
TE: No international appearances.
Watch for: They're pretty cracked, FengFs skill level is up there with the likes of EDG players imo. The rest of the team are also very cracked with players like Kai and HeiB to watch. They should be able to challenge EDG in the league.
DRG: No international appearances.
Watch for: Ascension winners, they beat RA. That's a pretty big deal considering the fact that RA was touted to sweep the tournament. Might not do very much and they probably won't challenge EDG in the league.
There are some other teams without rosters atm that could sign cracked players.
But overall, CN is still the weakest region but it is also the one with the most potential imo.
