confusion mesmer vs shatter mesmer
If by confusion mesmer you’re referring to the Blackwater mesmer build with rabid gear, then yes, you can 1v X very very effectively. I’ve killed many 1v2-4 with BW and held off numbers much greater than that. It has insane survivability if you use your stealth well.
Shatter builds, check out Osicat’s shattercat builds, can 1vX too but I’d say it’s a lot harder to pull off than on condition builds. You have less survivability through stealth/buffs and really have to set up your shatters well in order to land all the clones on one target. If you pull it off though you will be downing folks really fast.
