Low level Enchanter spells?

[Korain]

So I recently made an Enchanter on blue as they're much easier to solo with than a Monk. I was looking over the spell list, and I was curious about which spells were considered "best" or "required". For example, I notice that Enchanters can get Lull at level 1, but then they get Soothe at level 8. Is picking Lull up worth it just to replace it with Soothe at level 8? Is Lull perhaps better because it works on the same mobs and has a lower mana cost, regardless of the lower duration? I've already read the case for the first mes spell over the rest, and that one makes sense, despite there being little room to do much else during.

What level do groups typically start asking for Enchanter buffs as well? I am going in with the assumption that first level strength spell and such are likely not worth the investment.
