(sorry if this was posted elsewhere but I can't find any discussion about it)
I really like the launcher style in many game (just as in LoL), I think you should implement it in Valorant. Being full screen in the lobby is a pity, it feels bad when waiting in the queue, you can't surf while waiting for you friends (or have to alt-tab). It really improve the game feeling. TBH I think this is a requirement for any e-sport game nowadays. Best option would be to have a "riot launcher" including all your games. Currently we have to start LoL launcher to see if we have any friend playing LoR / Valorant, then swap to corresponding game when required, which is a pity.
Hope this reach you !
