I that NAVI, LEV, and DRX have all had issues rooting from the fact they kept the majority of their roster. Dont get me wrong, this doesn't create issues by itself, but all three teams held onto a LOT of core strats, playstyles, roles, and comps, that make them incredibly readable. The reason why the top teams are the best rn is not because they were the best last season, its because they've learned how to move with the meta and truly play new valorant, not the same valorant with 1-2 more new players. If any of these three teams wants to truly succeed in my eyes they have to make some massive strategic changes, the core of each of their playstyles has become so readable to the point of them losing matches against much worse teams.
