With all ranked worthy maps available in the pool, there will be allot more chances to find a common map between you and the opponent. As for arena players, the map is popular enough that they will have good odds of sharing it with another player in the star section, alongside other such maps like hideout or otherwise. Similar story with those that enjoy nomad types, they are still likely to get their preferred maps because the map/game mode is popular enough that the odds of them being matched with a like-minded player is going to give them more nomad games than current, not less. This pool type increases the odds of finding a common map that is good for both you and your opponent, rather than your wanted map types all being banned and never gotten and being forced into a map you’d rather not play because there aren’t enough bans, it is much better than having infinite bans or choosing only one map and queue times being increased tremendously grievously. This is the best option, having infinite stars and no bans.
Under the current system, you are far more likely to have your preferred maps banned by the opponent, and for the opponent to star their map and gain 100% odds of getting it because you banned your ‘worst offenders’ list and didn’t have enough maps you actually like in the pool and the opponent has free reign on the rest of the pool to place their star and bans.
Under the infinite star system, an arena player will have infinitely more odds of getting their map against someone that stars everything but arena, because it’s better odds than 100% failure because the opponent is not forcing the arena players to not play arena by outright banning it. the odds in that situation are better for the arena player, And arena is popular enough that they will be able to regularly play arena or some other similar map.
In fact, under the infinite star system, players who want to play a single map and only star a single map have far higher odds of getting that map, 100% odds provided the opponent stars it alongside their repertoire of preferred maps.
You are encouraged to broaden your horizons of maps rather than have a limited pool, but you certainly will not be punished for having a limited star section, for instead you are encouraged to find a map between you and the opponent that you both may enjoy, and that means the odds of finding an opponent that stars your preferred maps is far further increased than current, especially with all ranked worthy maps in the pool at once.
Under the unlimited star system, the upsides far outweigh the downsides.
Under the current system the down sides are practically equal to the upsides, and under infinite bans there are far further downsides that infinitely outweigh the ‘upsides’.
It is better that the playerbase focus on maps they enjoy, and the infinite star system allows them much higher odds that you and your opponent will have a shared map between you that you both enjoy.
The goal is to keep queue times the same or better while increasing the player satisfaction ratio, and this is the best option. That, and alongside this change creating an in-game ranked elo system in the lobby area to give all accounts a ranking.
