So... making Tryndamere a little bit more serious?

I really love his lore and I really love his brutal northern persona. But I think that he could have some tweaks. Why does his W, Mocking Shout, make enemies sound like chickens? Seriously, chickens? Why is it so comical and why it doesn't fit him? His legendary skin, Demoblade Tryndamere, which was supposed to be even more brutal and even more nightmarish, is also making his enemies sound like chickens with the chicken icon above them. Isn't that ridiculously funny? Also, his joke. About his right arm. Yeah, yeah, call me pervert. But don't deny the fact that you didn't think about his giant sword in the first place. You thought about Tryndamere's trainings when he have a free time. Considering the fact that now him and Ashe are no longer husband and wife, you can clearly see that he sharpened his right arm technique to the boss-like level. On a serious note, it couldn't be that embarrassing and it calms his "kill-them-all-or-die" character a little bit with something hilarious and unserious, that's a real joke one champion can have and live with it. But a combo of his strong arm and chicken mocking shout is really out of place, so I start questioning myself - is he a serious character or a comical character? Was Aatrox sure that he has chosen the right person for his dark plans?
