Personally, I'm extremely excited for an upcoming Preservation character named Adventurine. "Preservation" = Tanks/Shielders

His kit's still not officially known, but the rumor is that his main focus is on protecting the party with shields that also increase the party's resistance to debuffs and building stacks of his unique passive anytime his shields are attacked by enemies that result in a powerful counter attack. It also seems like he's going to have some supportive elements too, such as increasing the damage enemies take from critical hits.
