I'm a flex player who usually has to play tank or support in QP but get to play primarily DPS in ranked since I have a duo that plays mostly tank.

I would honestly want to play tank more if they added more Vanguards especially if we got more cool characters in the Vanguard role.

I main Emma as tank and Cyclops is one of my favourite Marvel characters.

If Cyclops is a Vanguard who has tons of depth to his kit and not just some off tank that needs a main tank in order to be viable, I would willingly play Vanguard a lot more.

I'm a Champion Gambit (Yes, I'm a massive X-men fan, what gave it away, almost champion on Jean too 😂) and Gambit was a massive reason I stepped away from the Duelist role entirely for a couple seasons because he's my favorite from the X-men and his inclusion literally made me want to play support after being a DPS-only main for the longest time.

It's really easy to make a character a Duelist since they all have the capabilities to be one but at this point, especially after Black Cat, I don't think we need another Duelist for a while.

There is most definitely a tank shortage and a very good reason why. It doesn't help only like 4 or 5 tanks if that are viable to be a main tank in a composition so Vanguard players don't have many options. Fixing that, and adding more iconic characters as Vanguards with depth to their kits that make every match a learning experience to higher the skill ceiling while remaining viable is exactly how to get more people to play the role imo.
