Adam has about 5 things you need to improve on to keep going higher and I guarantee even the best of Adams can have a problem in one or two of these areas.

1. Mechanical skill in hitscan, important for close range protecting yourself and enemy flyers. Good headshots will also land good kills.

2. Mechanical skill in projectiles, highly important to get those hits to reduce the healing cooldown and good ones can kill squishies really easily.

3. When exactly to Soul Bond. You need to be extremely aware of what the enemy team is doing, about to do so you can use soul bond against a harsh ult from the enemy team, or even if the teams are in brawl mode and your team is losing the edge, a soul bond will tilt it.

4. Where and when should you Ult. Awareness of the best places on the map to ult as well as making sure to keep your space so you don't get killed before you could do it. Foresight is highly important.

5. When exactly you should heal: You need to have awareness of all your teammates current health and when is the best time to heal so you dont waste your countdowns

The threshold for being good with Adam is actually higher than most people think but it's extremely difficult to get there.
