How can I follow Valorant roster changes and identify promising new lineups?

[MichaelOM]

I'm trying to get more seriously into following the competitive Valorant scene this season, but I'm finding it difficult to keep track of all the recent roster changes and team compositions across the different international leagues. I know some major organizations have completely rebuilt their lineups, but I'm unsure which new player combinations are showing the most promise or synergy in early tournaments. For dedicated esports fans, what are the best resources or analysts to follow for timely and insightful updates on esports team rosters and the strategy behind these moves? How do you evaluate whether a roster shuffle is likely to succeed, and are there any under-the-radar teams with new lineups that you think are poised to upset the established favorites this year?
