Having played a Spellweaver to level 9 and retired, I'd like to offer how I'd re-balance the class.

Main nerfs:

1. Cold Fire is a loss.
2. Inferno is a loss.
3. Mana Bolt initiative swapped with Hardened Spikes initiative.
   

Main Buffs:

1. Nonsense healing losses on Freezing Nova/Icy Blast now re-usable heals.
2. Forked Beam grants Elements, Spirit of Doom now has a reasonable floor.
3. Twin Restoration re-designed.

​

And quite a few other small changes. The main goal was to preserve the "feel" of a Spellweaver as she gains levels - relying on powerful losses, with the ability to burn extremely bright to swing the tide of battle at the expense of stamina.
