i disagree. I find it to be an amazing ability. Everytime I use it, I hit for about 200 damage. That's almost a full cure's worth of mp back. Granted at level 18 I have to cure 2-3 times a fight, but i'm also using radiance quite a few times during fights especially because it tends to give a nice exp amount. If you play conj by just buffing - shock spikes, (protect, shell) and then casting spirit dart, you will use up exactly half of your mana every 15-20 mins. It is plenty of time. You will also notice a greater increase in EXP if you stop nuking. It is alright to nuke occasionally, I tend to start fights with nukes, but Spirit Dart will be your primary attack.
