If W.Klitschko had a Russian 'I must break you..." attitude he'd be more interesting.

He doesn't have to act anyway. He just has to fight a certain way. He can still be a well spoken professional athlete and still be a ruthless killer at the same time. If Wlad fought like GGG or Kovalev instead of boring ass Andre Ward and Floyd, he would be a revered Heavyweight Champion.

He isn't Russian

Then he'd take more risks, get hit more, and be ktfo every other fight.

Exactly. Wlad's style helps him with his suspect chin.Which in the aspect of being intelligent, he fights his fight and makes his opponents do so. If Wlad was more aggressive, his chin may just get cracked...again.
