Having a build that does most of the work leaving you safe enough to use the crappy weapon does not mean the crappy weapon is any good. Handmaiden bladedancer builds to clear hordes, steroid build to just brute force any weapon into working, waystalker hagbane etc.
Generalizing? I am realistic, again.
Vast majority of maps wont offer such nice spots that lets you trap the boss into standing on the wall until it explodes, and commonly your teammates wont have the peace and space to kite a boss around the wall with enemies pouring in from all directions.
You just said " be mindful of the terrain and look for spots" which sounds like a lot of bogus to me. Especially given how few maps actually dont offer multiple points of access for enemies to walk around.
That it can be, but, if you dont kill enemies in that space you will generally just be back in that spot a few seconds later.
Only if they are standing pretty much on the wall when it goes away, how often will that happen in a moving fight? How often can you just stand in the same spot with specials around?
How often will enemies actually pile up ontop of eachother so much that you can make a meaningful difference with a wall?
Your statements are hella vague too!
I am doing a comparison, the wall is generally useless for blocking enemies and the stagger is so light while the followup is so weak that it just doesnt help most of the time.
Even a bit of bad luck with specials and suddenly that wall isnt helping your team at all but helping enemies instead. Bloodrazor meanwhile just kills things which is very straightforward but also very helpful.
Plus, if you do a bad funnel you are just promoting hyperdensity which is a problem all on it´s own. And if you obscure sight too much then specials get a free pass to close up on your team which is extremely deadly in many cases.
Heck some specials like gasrats/Stormers can just ignore the walls at times and just do their thing anyway.
