Indeed. The removal of the healing spell will require a major adjustment, but in the end, I think it was a good idea, because out of the initial three tier 1 spells, there was usually very little reason to not go for the heal, because it is an ability that is always useful, and scales very well. It was an oppressive ability, when it comes to making a choice in your spellbook, if you catch my drift.
Not to devalue the ''iconic'' ability argument of course, it is definetely a valid argument. However, you can see that Edain puts more emphasis on uniqueness or a niche if necessary.
Nevertheless, it remains hit or miss. The new Grey Company has exceptional utility, and utility always shines at higher levels of play if you know how to make use of it as a player. I predict it will be a hit. We'll see about the removal of the heal spell. That will probably be a tougher pill to swallow. Maybe we'll see Wells now? I certainly hope so.
