solari is the only good item but it is more on the support side
And what's wrong with that? It gives decent health, a little magic resist, cooldown reduction, boosts your allies magic resist and health regen, and has an active that doesn't required targetting because it hits EVERYONE.
This is a team game. Just because an item can benefit everyone doesn't mean it isn't good. A tank is a frontliner, but doesn't deal as much damage. Your role is to protect your teammates, not just soak up damage like a sponge. Making your allies a little durable too will protect your TEAM's main damage output, which can save your ass in a pinch.
The support isn't the only one that supports the team, the tank isn't the only one who protects the team, the carries aren't the only ones taking objectives, and so on.
