You don't have to be level 35, he just over did it.
You should be fine at the level you are.
ya i was just saying what lvl. i am, you guys you will be fine at lvl. 20 or so like KOG said. I spend a lot of time leveling them up so they will be stronger than expected, it takes a while though so unless you want to spend your time just beating the game then don't do what i am doing by leveling up all the time
