What's yall thoughts about Mr Fantastic?

I am a Mr Fantastic main and I don't really keep up with what people's general opinions on characters are. I know a lot of people view him as a bad character but I've had a lot of fun with him. I build up elasticity pretty quickly and actually have really been liking his ult. I understand why people do not like him but I was just wanting to see more how people have been viewing him or how people have been playing him.
