Torches
Along similar lines why don’t you ever run out of arrows or bullets? Where is your backpack and the other 4+ bags you’re apparently carrying? Why can you fill this invisible backpack with greatswords and longbows when realistically even 1 would be too big?*
It’s one of those things where practicality over-rules realism in the game mechanics. In reality yes you would have to light your torch each time you wanted to use it (either with magic, flint and tinder or whatever other method) but it’s just not worth it for players or game designers to put that in, so they didn’t.
(* For the answer to those last two questions google ‘hammer space’. Not to be confused with hammer time.)
“Life’s a journey, not a destination.”
According to a certain Asura at a certain skill challenge, everything and everyone is magical.
Ever wondered how Ranger manage to call forth lighting just by rolling back?
What, you can’t create lightning by rolling? Its how I jump start my car sometimes.
But ya, even non magical professions in the world still have some level of supernatural power.
Rangers do use magic, ThiBash. They might not have in GW1 (outside nature spirits), but they do in GW2 – it’s how they differentiated themselves from the other adventure professions over they ears, in lore (where engineers went full technology, and thieves went with a mixture of tech and magic, rangers went no-technology).
Given this, I believe every profession which uses a torch is a magic user, so it’s less that torches are magic, but that the professions use magic with the torches as a medium.
Stop treating GW2 as a single story. Each Season and expansion should be their own story.
