Let's talk about Mundo

So,i've been having issues with Mundo,whenever i played in lane against him,i lost 80% of the times,thought he was OP,just some salty stuff. But then i decided to play him. 4 second cooldowns on most of his spells,seems ok. Am i the only one having issues with his broken Q? Like,if you dont dodge the first Q he throws,you're not dodging any other Q's,which lead to your own demise. Yeah,you can kite that first Q,but if you dont you will most definetly have to waste a flash,or just hope someone comes to help you. I suggest that if he hits multiple Q's on the same target,the slow decreases by a %,it would atleast give you a chance to run,because if he hits you with one,he's gonna hit you with each other that comes your way
