It depends, the game has gotten much easier, i started with a little turtwig like you, except i had a breeze with corey. You probably got better from experience though, i know i did. Throughout the whole game, i was always 10 levels below EVERY gym and i still win with pure strategy alone. I beat terra, with level 50 pokemon. But you can't win this game even if you know what exact moves and the exact chances and damage the opponent will do. Like a lot of people have said before me, you can't be prepared for reborn, its so difficult that levels, even level 100s won't help you, strategies win games. When i fought noel, i lost every time to clefable, and when i just changed one move to another, i won. Goes to show how different each play through of reborn is. I had no idea where I'm going with this, but I'm rolling with it.
