Woah there, Nelly. Slow down and remember something.

1.18 is the "foundation" patch.

On this foundation, Conjurer is designed as a solo-class. Right now, you are partying as if you were soloing - each player should still be looking out for themselves somewhat. That means if your fellow Diciples of War are not throwing up the occasional Sacrifice spell to keep themselves going, it's their fault if you - a solo caster - can't keep them alive on your own.

Now with the foundations laid, party-based classes will be next up for implementation. Then you can become an actual white mage rather than play a conjurer pretending to be a white mage.
