Yes you're all so smart and sagely you want A Realm Reborn Reborn. I'm sure the game could sustain that.
Well for the masks I think that's probably just as much the effects as the stats, that's a little like pointing to the Orb of Deception and stating that WoW too has gear people seek 9 years afterward. Definitely I'm not disagreeing with you EQ 1 had a ton of horizontal progression, but pointing to a Clicky and Twink Item as 20 expansions of horizontal progression falls a little short. Unless the Barbarian mask is still BiS for rogues or something.
The constant desire to argue horizontal progression as a no-thought required panacea to all that ails us is just really tiresome. As are the drawn out comparisons to older games that are still 'going strong' thanks to horizontal progression. I mean if there's such a great horizontal progression MMO market out there why not play those games you keep using as examples?
