Any archer spell names we have are just interpretations of Korean or what people have invented.
I've played the Archer on official Korean, only at a relatively low level but you have to play a bit like a wiz. Attacking from range, maintaining your distance, choosing suitable spell for the monster and line of sight etc. It might be a bit different at lvl 40+.
So yes, it's different and in Mir, anything different is welcomed, it creates demand for new items and new spellbooks etc. but I don't think it's an earth-shattering class.
