I’m having fun with the Transformers: Robots in Disguise app/game. I mean it’s free, looks good, the gameplay is fun, and it has a lot of characters to unlock.

But as soon as you unlock the strongest versions of Optimus Prime or Megatronus,

there’s no real incentive to play as any other character nor to gather Energon to unlock more of them.

It’s such a shame that there’s no option to upgrade characters to make them viable at higher levels.

Alas, poor Strongarm, I love you but Megatronus has better chances of survival.
