[@Aeolian] [@Animal] The way I also interpreted it for myself was that while Marko might have a general attunement like "Fire", it will exhibit differently than others with the same attunement. Marko can start fires and may have the ability to generate explosions, but its possible someone else can manipulate raw flame by shaping and controlling it or something to that level.

I'd even say that someone could be attuned to Earth but only manifest that ability as crystals, or be attuned to Plants but has special focus on flowers.

At the end of the day characterization is going to be a lot more important than the chosen element, which I think is big and flashy but not necessarily what's going to make each character special on its own
