title,when and how
The only issue I have with this system is that teams will need to prepare 2-3 compositions per map to even have a chance. If you prepare just one composition and one of the agents on that map gets banned, you're screwed and automatically lose that map. This forces teams to play worse, which ultimately makes the whole scene worse.
This forces more competitive play. And if you're a professional player as the game evolves, they will adapt naturally. A pro player in the future should at least know how to play 2-3 agents in their role professionally. If we keep seeing 1 trick Jett duelists over and over again, the game will get boring and Valorant will fall off. Imagine seeing the same Ascent comp again and again for the next 5 years. But yes, its the pros job to build and play around great comps. If they fail that, they're not worthy playing professional. The level of pro play will definitely increase as more maps and agents and shifts in meta occur in the future.
with the current amount of characters, pick bans will only decrease the level of play. valorant is a massively prep-heavy game where teams will practice specific combos and antistrat those combos
games like league where there are so many characters you can ban one and there will be another fairly similar one that plays the same don't suffer from this
id honestly argue you'd need atleast 10 characters of each role for this to be viable
