^Its not a problem of the gear system, but gearing itself. Altho horizontal would actually make it easier; since you can provide more options at the same ''ilvl''.
Vertical progression makes new gear desirable* by having it be better in most cases that previous gear and also having different models. Horizontal progression has a tendency of making only a few pieces desirable until better pieces appear.

*Not interesting. Interesting is a bad term. Anything can be interesting if it is different than normal. A left side tank piece with +Mind +Spellspeed would be interesting, but not desirable.
