Question On Excalibur

I'm very bored ingame, and something to keep me going is working on a relic weapon. Before any such things, yes I have the means to obtain one. I'm a mage-player who has no melee leveled, and I don't care about most things, so I was gonna do Mjollnir because whm is totally awesome and I've always wanted to be running around dual-weilding and wearing my crafting gear with a Mjollnir.

A friend tells me to not do it, as it's useless because it's blunt dmg (I know) and if I really want to melee and have fun on mages, to just do Excalibur, and that I'd look cute with a sword. So I'm wondering how it is meleeinng with one. The en-dmg effect looks sick.

And I'm buying all my currency and probably buying my attestation and fragment and necropsyche, so I'm not wasting anyones dynamis time.(In fact I'll most likely be lowmaning cities with a group of friends, we all split glass cost and split all currency, just a way to save a little gil) I hate the system of dynamis so much, and I wouldn't screw others over just for myself.
