Something for us to rejoice about!
With the "safe" exp camps all clogged up, exp parties are having to explore a bit more and take a stab at more dangerous areas of Vana'diel. This is good news for WHMs, because nothing helps out a dangerous place like a WHM.
I was exping with a group on RDM in Xarcabard (S), but they asked me to run to change to WHM because of 1. R3 2. Banish bonuses and 3. Better buffs in general.
Then I was with a group in Caederva Mire, and it was in an old school party with a PLD, two strong DDs, a RDM, a WHM, and a bard.
Areas with undead infestations and difficult mobs lend themselves to a WHM primary healer. I suspect we'll be used a lot more frequently in the coming months, as people explore more dangerous areas and need a solid backline again.
