I can understand and appreciate why @Omicron wants this new system. I can see that if players just used a abyssal whip/tent everywhere you'd inadvertly be making weapons like the Abyssal Bludgeon worthless since you can just use the whip/tent at KQ, Cerberus, and other bosses that should require a different niche weapon to attack.
The ONLY thing I didn't like was the major change in damage, and/or accuracy (thinking of things like the Gauntlet, Kree'Arra, and other bosses that are taking 2x as long to kill as before). Reading the update originally it made me feel like bossing would actually be quicker than before if using the right gear, but even in BIS post nerfes bossing still feels much slower even with proper gear and that's what I hope gets taken into account more and gets tested much more from this system and the old one.
