I want to feel different and unique (PvM)

I've played lots of "optimized" templates, most recently I'm playing a HW/Shield/DF/DW, Void/Summon, Missile/Summon, 2H/Summon (sensing a trend?). All 3 school (4 school for mage obviously) self-buffing.

Was thinking it would be fun to play some "non-mainstream" templates, something different from the usual.

Looking for suggestions of things that are different from the usual and fun and/or challenging.

Thanks!
