If they made healer on the fly casting meaning, being able to cast spells without getting interrupted when you move, I would be more interested in the job.

I mean monsters can hit you and interrupted you but for once I would like to see a healer who can run and cast, with all the dodging you have to do I feel the casters get the short end of the stick.

meaning paladin needs heal on titan but has to dodge rock slide resulting in tank dying, seen it happen many of times, because the healer cant multi task very well.
