Poll: Gear progression, horizontal or vertical?

[Songi]

Important to ask the question, though: If it was so great, WHY has no other game managed to even attempt to come close to it?
horizontal progression systems get very, very murky and impenetrable, since in order to be viable for all those situations, you need a different set for each one, which means grinding out those sets. And that increases the impenetrable nature down the line when they *MUST* introduce new content and gear. DAOC ran into this problem head long, and so has every other MMO with horizontal progression.

It's a very casual unfriendly system.
