Wow thanks for the many replies guys!
So I'm leaning towards a few specs now: Staff Mirage & Heal FB.
Scourge has too much of the death theme I'm not that interested in, and ele would be another contender which I might give a shot in the future but I don't like many builds I see and the fire skills, I'm more interested in a mage that shoots lightning bolts and spells from far away to do damage, and not use them just when the need arises for the utility.
So I have a few questions:
For group content staff + Axe/shield heal FB are considered best I've seen, is that right?
Which weapon sets are recommended in open world content when going solo with FB?
And ginally as for ele, anyone has some links to a good build for group content aswell as a good one for OW, using staff only? And would it hurt to leave the fiery GS elite out? Because even though it's a magicql weapon you summon just to swing a few times, I'm not much into the conjuring style and would rather focus on just casting spells.
