I have never, ever, had problem find a party with SE.
If anything, I get annoyed by receiving constant invites, when I enter party finder.
Where do you go pre 76?
Catacomb, LOA, GC will invite you for the stigma.
Every mag party will invite you for recharge.
In the Rift, 40-70 there is always dedicated healer, so you are playing recharger.
Archers in Pavel Ruins are happy to have you. (they are happy even with buffers in transform)
Mana up/Conversion C grade item for 5kk, and kookaburra. That's all you need.
