Wisp enchanted rares are invincible most of the time

Honestly, rn it feels pointless to run the league mechanic aside from getting cosmetics. Wisps gives enemies so much health that its better to skip a lot of the enemies from other mechanics cuz of how things stack toghether. Wastes too much time to kill a shitty rare, beast, essence or harvest enemy, when you could be blasting thru maps and mechanics without wisps. My character is considerably melting maps by itself, but when i run the wildwood, 70% of rares and stuff like that gets invincible.
Rn its better to run the wildwood at the end of the map for the cosmetics, ascendancy and items, rather than using it for juicing maps.
