The problem is you've worked up speed first which is a minor on a Hard Hitter. I'd suggest starting over.

can i change it to COmbo DEfender? and how can i do it!?

No, you selected the archetype when you started. It's too late now. If you want to change it you have to start a new player.

crap ¬¬, so what if i started to train and focus on strenght!?

You can do all kinds of stuff. However, you'll always be at a disadvantage against your peers who built properly.

What I'm getting at is that there's nothing wrong with keeping the player and changing to focus on your majors now. But you'll never be as good as someone who built with the majors in mind from the beginning.

Here's my level 17 hard hitter. He doesn't boost, but he's been built with his majors in mind:

Unbalanced now, but by about level 30 he'll look quite nice.
