Ranked Season Rewards for less attractive roles

Hello. I’ve been thinking how to encourage players to fill roles in lower divisions such as silver to diamond.

When the new season begins and we have to play those 50 games to get cosmetics or gold. We could use quests like 15 wins as one of the roles such as Tank Healer, Bruiser, then the player get rewards a possible portrait or spray.

If the player make 30 wins as one of those roles a possible new unique skin. When achieving 50 games as one of those roles an unique mount.

Keep in mind wins not 50 games in total and since the season lasts at least two months there will be plenty of games to play and doesn’t mean that the player can play every game tank.

While Ranged Assassins are top pick because of the damage role rewards for that role would make players only to select that role which leads to unhealthy game.

World of Warcraft had similar reward system with justice points for dungeons since there was always dps but no tank and Heal.

This idea might have been suggested before in the past probably by another forum user but it’s the only way we could encourage players to fill those roles and make the game challenging.

Lastly those rewards should be only earned by completing those quests not by opening loot chest.
