As JG said, the main reason people tend to avoid melee (initially atleast) is that they add a bit of difficulty. That being said if you are up to the challenge or just revel at the prospect of shiny new buttons to micro manage with, then go for it. It's all viable, but just expect to encounter new obstacles and annoyances

I always found it more important for my enjoyment for me to genuinely like the setup and characters over having the absolute maximum output possible (as long as I am not hitting an absolute wall), so I absolutely understand the desire to run even silly and wonky comps just for the fun factor.
