It is clear now that all teams need a sixth player. What role done you think would be best for that extra player? I think an extra igl that can act as almost a secondary coach makes the most sense
Doesn't matter. Majority of the 6th players will be just bench warmers from tier 2/3. No player with actual potential or future would accept being the 6th player.
6th players must be a competitor for a player that somehow lacks compared to other teammates. if a team's initiator has something to improve or there are much rooms for improvement, i think the 6th player should be initiator main to make both of them compete and improve.
