On a level 20 charmeleon?
Some of my mons barely have more than 40 HP, and none more than 80.
So it 2-shots everything, and is faster than all of my dudes...
This is why Dragon Rage is a horrible move guys. Super OP early, and useless late (except for ease of weakening for capture, I guess).
Sonicboom, on the other hand, somehow never ends up being really overpowered.
