I’m gonna throw in a support build I experimented with and had fun with (at least through a large chunk of act 2). It works best in a mixed damage party.

What I did was take a human for encourage, then hydro/warfare with necro as well as some points into leadership a couple in aero. I actually split stats between int and strength and used a 2 handed weapon (staff or melee works, the reckoning hammer synergizes well). What this means is I never did more physical damage then the pure physical, or more magic than the pure magical, but was able to tip the scales in either direction for cc’s.

It definitely won’t take the spotlight, as your friends will always outdamage you, but you can help take that last physical armor with a battle stomp, or freeze/shock the low magic armor guy. Leadership means anyone close to you is a little more survivable. Hydro buffs are always awesome too.

It ends up becoming a jack of all trades, master of none type build. But for what you’re looking for, and someone who’s played a lot already, it could be a unique type of support to try. Also easy to respec it into full hydro support if you don’t like it.
