To whoever said that Evans do suck at bosses.

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.

You're splitting hairs here. Archmage isn't a bossing class, it's a training class. A bishop is a support/training class. These things are obvious. An archmage barely if not is weaker than a dark knight unzerked. A fully buffed night lord does nearly 1/3 more than a dark in zerk. Unfortunatly I can't pull up the damage chart located on this site atm but you can see for yourself. If evan is weaker, or rather on par with an arch mage, doesn't say much about their DPS. A good bossing class is one that has staple support skills and has comparable damage. You can argue that because a character can do damage on a boss it is automatically a bossing character but thats a skewed view. And I won't ever turn down a friend who happens to be an arch mage for their DPS, but I won't lie, they are there because they are a friend of mine, not for their DPS. There is a reason, in speed runs, you see no mages at all. Unless it's of course an all mage run, obviously.
