It's called Battle mode, not ladderclimb/roofhug mode.
To counter the typical "but ranged is weak and needs that cover" argument, take a good Archer. He (or she) can clean your clock without that silly playstyle you think your "class" needs to be competent.
It's fine in strat, fine in siege.
But not in the typical Battle map. It just messes up everything even more.
Think about it please.
For those who think that ladder use of this is a must to stay competent:
In short: If you need to hide your ass up there 24/7, then quit ranged. People do fine without it anyways.
