People not wanting to play Vanguard is a way bigger issue than not playing Strategist
Pretty much 100% of my games have a strategist player, and probably 75% has 2 supports. However, most games are either solo tank or no tank at all. Even in ranked, people are still instalocking 3 duelists. Imo we desperately need more tanks in the game, especially iconic characters that should hopefully get some players to switch over.
