Yes clang buys you time...its a big part of the whole melee strategy, if you can't roll you go for a clang ..or a hit.. or dont want to roll you can clang to mitigate damage etc You basically trade weapon dura for armor or health.. it also buys you time to regenerate armor mid fight. As for Staggering.. Altho you never really notice any of this.. I can clang a player or a wall with a chainsword on a mace and go straight into a roll or heavy attack or whatever.. I can post video of this if you like. So I'm kinda unsure now wat stagger your talking bout tbh.. We are talking about clangs and not weapons breaking or frontal heavy attacks from axes ... right ?
