it seems as though every game, no matter what, has a shortage of priests, clerics, monks... whatever. There's just no healers to be found. I have countered this by making two straight healing characters on my account, one PvP (Fi Boon Healer premade) and one PvE.
at first i thought i wouldn't like it. after all, who cares about helping other people when you have to option to tank and do craploads of damage. and monks armor! its so weak compared to warriors and rangers!
after playing though pre searing and doing a few tombs/competition arenas, i have to say its one of the most satisfying experiences ever. has a big bad warrior come to hack and slash me? healing breeze. retribution. done. oh NO! has Mr. Firestorm come to annoy my pack of spellcasters? heal other. infuse health. well of blood (not a monk skill, but hey, i use it).
i enjoy not dying and keeping my health up. also, its a very exciting job. one may think that it's boring not killing anything, but its actually very hectic. balancing your energy, health, and party member's health is a difficult task indeed. but its so rewarding.
and you know what else? I'm sick of spamming "need healing monk for mission!" over and over and over and NEVER getting one. if i say "need one healer and a few tanks/eles for mission", i get four or five warriors and casters, and not one monk.
and everyone complains that alesia sucks, yet they don't want to be healers.
help the world out and have fun at the same time! invest some points in healing magic!
