I'm with Outkast Dev here. I don't personally care what a shard uses. Each has their good and bad in my book. I probably like AOS the most due to the complete randomness of it all; nothing same-ole same-ole. If you are worried about mindless dexers, go for the high physical armors and cast protection before you enter battle; chances are, you'll win.
I didn't play OSI Pre-UOR but I've played a few shards that 'immitate' it. Kind of boring, hunting is useless, and most of them are basically full mages with Explode, Flamestrike ganks.
I didn't play OSI till UOR. About 3 years ago (??) it was fun, awesome, new, original (to me, hell it was my first MMORPG), but wow, that was FOUR years ago. It got old. Didn't enjoy hunting, even PvP got a little stale now and then.
Seige Perilous. I watched my brother play it. The only thing I didn't like about it was how many people are murderers. I don't mind murderers, but for the love of God, let the 25 str newbie kill a skeleton, please? Carrying on...
AOS, mostly for it. Custom Housing, hell yes. That might sound Trammie, but decorating happens to be one of my top 5 things to do on UO. Special Weapon abilities, most of them are alright and well balanced. Some with some tweaking would be exciting! The resistances, painfully annoying to get a just right set of armor that won't hinder you in battle, but it's not *that* bad. The only thing I'd say get rid of completely is INSURANCE! Lamest idea ever. This is a PvP game, because you go out and stake something when you throw down the guantlet and retaliate. Take out luck and AOS is win.
I don't even remember what else is up there. Pub16? Don't know which pub is which, so whatever.
PS: I don't remember what I voted for, probably wasn't even AOS.
