Pro tip: Tell me you're new to a dungeon /rant

But wouldn't it be safer to assume they are new?

There's really not much reason for alts in this game.

actually theres quiet a big reason for alts. You can only get 450 poetics a week, with alts you can gear up more. I assume you can do raids with alts even if you have completed them with your main. So yeah there are big reasons to run alts'

Then there are other reasons, like there are many different races you can play, and you cant be all races on the same character so then you will be needing alts as well.
