Hybrid.

Not exactly what was talked about in the OP, but I'd prefer a slower vertical progression with more interesting and potent stats that don't necessarily appear on every piece. For example, most pieces would probably have more stats to them and some of them very potent like double attack, or at least interesting like enhanced regen/ refresh such that something with 'good' stats at ilvl 200 isn't necessarily outclassed by i220, but almost certainly is by i240 or so even if it doesn't have preferred stats.

EDIT: numbers given don't mean too much, essentially I'd like for some pieces of gear to be relevant longer rather than 99% of things being tossed when new gear comes out because it's unilaterally better.
