comprehensive overhaul of attackspells, including mana focus.

Mana Focus has been reworked into Raging Flames and boosts the fire skills Fireball and Blast of Fire. Shocking Fury, Explosive Frost and Lightning Bolt no longer receive a boost.

Lightning Bolt, Mana:10, Damage:17-19
...has been buffed to make up for the fact that it can no longer be amplified by mana focus. It remains the go-to ranged attack for Faren mages. 

Splash of Acid, Mana 10, Damage:16-24
...is almost unchanged. The rest of the system is balanced around its damage.

Explosive Frost, Mana:8, Damage: 18-26
...has been buffed significantly, pulling one dps ahead of SoA and still costing a little less mana. This is the new uncomplicated go to splash attack for Faren mages. Just like Splash of Acid, it interacts little with player resistances, the one extra dps and cheaper mana cost is a reward for chosing to go into Faren. If SoA was as effective as the equivalent Faren spell, there would be little reason to invest into Faren.

Shocking Fury, Mana:30, Damage: 30
...has a unique mechanic. It deals 30 damage without spread (but the standard SP scaling of course) and does not cost any reagents, however, this comes at the hefty price of leaving the caster unable to cast for 10 seconds and costing 30 mana. This will make the spell absolutely pointless as an opener, but a great finisher - also in PvE. A 10 second delay and the steep mana cost will make the spell hard to improve in a mindless, repetitive way, however, the spell will be easy to work while battling due to its value in PvE and lack of reagent cost.

Let's get to the new mana focus: Raging Flames

Raging flames is now a self cast only personal enchantment with no mana or reagent cost, but a huge vigor cost of 50 and a very short duration of 5 to 10 seconds, based on SP. Raging flames reduces the mana cost of fireball and blast of fire up to 100%, no longer increases any damage, but reduces the post cast time of those spells to 1 (from 2). This means: During raging flames, fireball and blast of fire can be cast at twice the rate, and free of mana cost. Vigor consumption remains the same though. During raging flames, fireball and blast of fire pull ahead of lightning bolt and explosive frost significantly, while falling behind big time without. The damage of fireball and blast of fire have been adjusted accordingly.

Fireball, Mana:6, Damage:12-14
This spell is now a good deal cheaper than lightning bolt mana wise, but will do way less damage unless used during raging flames.

Blast of Fire, Mana:5, Damage:12-18
This spell is now a good deal cheaper than explosive frost mana wise, but will do way less damage unless used during raging flames.

All in all, we have the following dps ranking of spells during raging flames:
Blast of Fire: 15
Fireball: 13
Explosive Frost: 11
Splash of Acid: 10
Lightning Bolt: 9

Outside of raging flames, blast of fire and fireball fall to the end of the field:
Explosive Frost: 11
Splash of Acid: 10
Lightning Bolt: 9
Blast of Fire: 7.5
Fireball: 6.5

This leaves the general damage levels largely the same, but gives Faren the option to get a little extra burst at the cost of a major vigor sacrifice (raging flames) or a complete lockout for 10 seconds (Shocking Fury), thus rendering all splash spells useful in some context. Splash of Acid remains the solid staple of Qor damage it has been.
