To whoever said that Evans do suck at bosses.

Even with PB's physical resistance, NLs and other physical attacking classes will outdamage Arch Mages. If Arch Mages outdamaged physical classes at PB, we would have killed it by now considering that Arch Mages don't have to be HP washed to survive.

Every class can boss, but some are better than others. 1v1 damage may not be the only important aspect of bossing, but those who don't deal exceptional 1v1 damage are brought for support/buffs. Arch Mages do neither of these. Slow isn't that useful at bosses considering that Warriors/Buccaneers can easily Rush/CSB bosses to keep them pinned.

Same goes for Evans. Their buffs aren't vital for most boss runs. Magical Resistance is their main selling point as a bosser, and that will only be useful at Pink Bean (and any stronger bosses we get in the future).

Including skill updates and apple, a Archmage will easily be on par with a nightlord, perhaps not outdamage him, although this is at bean himself, Archmages are still horrible 1v1ers at the statues which would be the reason why we can't go in there and own it up, but you are missing the point, there is situations at bossing where every class can do well, Horntail spam and at Pink Bean is places where Archmages can excel compared to other classes, and even with rush, slow makes things easier, especially if the warriors end up getting Kbed, seduce, or pwned.

In my opinion 1v1, as you said is not the only important aspect of bossing, and is not what determines what is and what is not a bossing character.
