Thor feels powerful and fun, but his mobility feels like syrup

Seriously, he's cool in a lot of ways (including art direction), but he just feels so slowwwwww. ESPECIALLY his ult. Why can he only move like 5 feet with it? His shift key mobility is a ton of fun, but it kinda takes too long to really get going. And forget about just walking around with him. Personally, I'd like to see characters like Thor and Hulk get a base-speed increase so they don't feel like tar when they move around
