im not worried about filling roles, imo the cascade picking just leaves the picking situation in an rng based system where some players will sometimes get punished having to fill a role they may not feel comfortable playing, ie: initiator, sentinel, etc
for a system like this to work, you need a similar system like league uses to not enforce players to fill random positions every other game, but choose from one to two roles they may want to play, that way cascade picking works just about fine
is it a solution to instalock duelists? sure it is, but it adds a different variable to the game; i guess we'll have to wait and see how it works out
problem for a preferred role based system is there are not as many agents as of right now to ensure diversity in queues, thats all my opinion tho
