Young Lando clarification and viability? Is he good, or not?

Most people I hear says he has good damage.

Thing is, that's all he really brings. Sure, there is the stealth, ability block, and potency down, but they simply aren't enough to compete in arena, and their are better (and more survivable) raid options (look at yolo). The team that surrounds him don't make up for the lack of utility

So while he's not trash and will outperform a decent chunk of attackers, he's often considered not worth investing in because he never was the best at anything
