The current BLAST Premier ruleset allows for teams to swap out players on their rosters in-between maps. However, this has not yet been utilized.
The only teams that could potentially benefit from this rule are Astralis and Ence, as they are the only teams that currently have more than five players on their rosters. In order to make this swap, all that is required is for a tournament official to be notified ten minutes prior to playing.
With Astralis recently adding Jakob ‘JUGi’ Hansen, as well as plans for Patrick ‘es3tag’ Hansen to join the roster, they will be the only team who might potentially make use of this rule. They have stated that their intention is to create an expanded roster, utilizing all of the players involved.
In Ence’s case, they will more than likely just use Elias ‘Jamppi’ Olkkonen for the duration of these events, as they have stated that he will be playing all of the non-major events.
In a recent report, Jarek Dekay Lewis stated that:
Danish Counter-Strike Tournament organizer BLAST is contemplating a rule change that would allow teams to make lineup tweaks at halftime of matches, according to multiple sources.
This has not yet been confirmed, however, and in the report, Dekay stated that representatives from BLAST have declined to comment.
The BLAST Premier Spring Showdown events are set to take place from May 31st – Jun 7th 2020 and will take place online and be separated into different regions. Each region will consist of ten teams, and the format for the group stage will be two round-robin groups, with each match being a BO1.
Even though it is slightly concerning that there are reports of BLAST seemingly making a rule change that would benefit solely Astralis, I am still curious to see what impact this might have on the game. My intuition tells me that swapping out a player during a map, or even in-between maps, will only be a disadvantage.
