Ideas for Gear Diversity

So I was thinking about something that would make gameplay a bit more diverse--special stats on weapons. It would make gearing a little more exciting because as it stands now, there is not a lot of variety aside from the main stat increase that comes from a bump in ilvl (excluding some classes who have a clearly beneficial secondary stat). I was thinking something like the Diablo-style gearing system, but without the RNG of a range of stats.

To give an example:

iLvl 205 WHM staff. Main stat is the same, secondaries still vary depending on the weapon. Includes a "10% chance to refresh Assize cooldown on cast"

Depending on play style you might choose one weapon over another based on secondaries and special stats. I love Assize so I would be all over a staff that let me use it more often! Procs would be just one way to make it more interesting... There could be special stats for mana/TP regen, etc.

Thoughts and ideas?

id like to actually see set bonuses tbh, i know we are meant to use other parts of gear for BiS but it would be nice to have set bonuses, the Eso gear could of done this.

It would definitely offer more options instead of the current trend which ScarletDawn pointed out. This is also something they had on RuneScape, and i liked it.
