Yes, there is a reason why you would rank magnum.

Magnum = firebolt -> 100% knockback.
AR = chain cast icebolt, if a mob with natural shield walks in on you, you will be dead no question asked. Besides, in intermediate dungeon, its all about the first shot killing a mob, it makes smash and magnum vital even with AR out.

Oh, anything without natural shield, AR will shred through like paper. But getting AR without magnum will make you cry. (Besides, remember what they say about skills - -|| they give you all the stats. An archer without magnum is like mage without firebolt *laughs*)
