Ah, that sounds perfect. Support/healer classes who can still go full offense is my ideal playstyle.The closest to a support class would be Techter, which has access to Shifta/Deband (area buff/debuff), area healing, and the new Overemphasis buff. That's not really your priority, though, you're still flinging Techniques and bonking things with Rod.
That being said, Techter main pairs really well with Fighter as secondary. Shifta overcomes the 10% damage reduction from using a secondary class weapon, so you can be up punching faces while tossing out heals to the group. Hella fun in UQs.
