so before .51, everyone hated the autoclimb, and i did too. but now, i am loving the autoclimb feature now that it has become smoother! Now that this addition has been added, i personally think that sprint could become appropriate.
Thoughts?

I'd be alright with a sprint, as long as it only lasted like 10 seconds and had a 20 second cooldown. Or something not too overpowered like that.

Ok, but if we add sprint, we have to slow down the default speed of the players. I think we are unnaturally fast.

I don't really think we're that fast. As a sniper, we could be moving a lot faster, you're all way too easy to hit.

That's because the rifle is too precise and our head is too big. I don't want to run faster to make myself harder target for the snipers. The snipers are snipers, nobody can run from them, just escape to cover, and thinking about sneaky counter tactics. And I think its more fun, than just sprinting zig-zag against a sniper and kill him in close combat.

There is no escape from snipers in this game other than tunneling under them. The going left and right thing doesn't work because like you said, our heads are too big. Sprint could save a lot of lives.

But I don't want to save a lot of lives. Snipers rulez!!!
(Saying that while I am not a sniper, but I love to kill them on a harder way.)
