Why don't you rp Ziggs like the maniacal character he is? You're kinda butchering him.
First of all
Second of all
Ziggs is maniacal in his work which means: energetic, overzealous and keen to prove himself one of the best.
What i guess you mean as maniac is violent and insane. I hate to burst your bubble but Ziggs is neither of those. He is a highly intelligent yordle ( ya ain’t dean by being a jinx ) that loves his work just a bit too much. In normal interaction I believe i rp him just fine
