So far the Cleric doesn't feel very... Cleric-y. He wears medium armor and shoots things with lasers instead of buffing and smashing. So far my only healing powers are a debuff that heals people who attack that enemy, a heal-over-time that heals myself as well as the target, and a minor AoE centered on myself that is mainly for damaging enemies. I just hit level 10 and unlocked "Divine Power" mode, which powers up my cooldown abilities and changes my basic attacks (one becomes a continuous damage beam and the other a continuous healing beam), but I haven't got to try it out much. It's also kind of hard to aim my heals because of the way the controls are set up, but I guess that makes the game different. It's certainly more engaging than healing in WoW.
I guess I just envisioned the Neverwinter cleric the same way I envision my 3.5 cleric - heavy armor, buffs himself to heaven and back, then smashes faces with a morningstar while healing people as an afterthought. And that's just not how this version of a cleric works.
