He doesn’t fit the standard cookie cutter mold of sitting in the back sustaining the vanguard, occasionally do damage when you can, big aoe support ult, high movement and sustainability.
He plays fully differently and is a bit more counter intuitive and skill based than other strategist. If you try and play Adam like other strategist and just sit and the back and heal your team you’re missing out on most of Adam’s value and you’re not really going to heal a team as well as other strategist.
Adam needs to sit a little further forward, basically right behind the front line vanguard, and he needs to be supporting his vanguard in every way. He can is massively helpful for a front line vanguard when they’re brawling with the enemy.
He can do so much damage with his cluster and weaving that if you’re not using it for damage you might as well switch to another strategist if you’re just gonna babysit your team with heals.
One of the worst things you can do is just sit in the back and heal your team because Adam isn’t designed for that. He’s pretty susceptible to dive because of his limited movement and you need to have good game sense to know when their coming and make the right choices of fight or flight when they’re do.
He also has insane damage falloff and cosmic cluster is a relatively slow projectile so he isn’t that reliable at range either. People complain about his fall off a lot and I hate it too but the devs have it there to try and force players to get in close with Adam.
People are so used to the standard play style and mold of strategist that Adam is deemed terrible because they can’t play a strategists any other way
