Inifinty Wizard set bonus not working?

[Actoba]

I finally got the wand to drop from Tower of the Shattered to complete the Infinity wizard set bonus but it doesnt appear to actually do anything.

Having only the staff equipped procs for a 1318 heal, and having both items equipped it procs for the same amount...and doesnt appear to proc more often either (just in case the intent was more frequent procs, and the set bonus is just badly worded, rather than a higher heal amount).

Can anyone else confirm this?

No-one else seeing this? Have /bugged in game too but just wondered if it was just me....
