Sorry for repeating his reasoning, but it seems like you didnt quite understand what he was saying. His point was that you use dont use int and mnd in the same spell, so you can switch out snow and aqua rings for basically the same effect. (this is excluding the -enmity, which he also said).Sorry, but if I remember correctly, RDMs needed INT and MND, so why exactly WOULDN'T you want the mage ring?
The melee ring's effect cannot be duplicated by switching in rings, because both stats are used at the same time.
Now, still excluding the -enmity and remembering you can only ever get one ring, would you rather have the ring who's effects can be simulated w/ slight inconvenience, or the ring who's effects can be found no where else in the game?
That being said, i got the tamas ring, lol.
