Skill Feedback: Arc

I have been using arc over spark as an archmage stormweaver because I don't like the spark playstyle/how it feels to play spark and I have some feedback on the skill.

1. I think the skill should chain 'faster.'

I find that in super dense maps, even with chain support and 12 total chains, I often cast again before the first arc has even chained to the next mob and I end up getting overwhelmed really quickly, despite trying out spark for a bit and not running into the same problem. It feels like past the first or second chain the damage is so lackluster and the chains take so long that they're not even that useful, even without chain support (afaik chain support is actually a damage buff for the first few chains with arc, since arc has 10% increased damage per remaining chain).

In PoE 1, arc would chain almost instantaneously, frying an entire pack of mobs immediately. That felt much better to play.

2. Decrease the penalty for the remaining chains by a little bit

The first strike and the first chain do good damage but the rest of the chains really do little damage. Spark outshines arc in almost all aspects currently. except maybe shock application but that is easily overcome by using lightning warp on ball lightning for shocked ground, or simply shooting a million spark projectiles, since its very likely that if a lot of projectiles hit, shock will eventually be applied.

3. Buff arc's base damage a little bit. I have not found a way to make it consistently outperform spark in any scenario. I feel like arc was going to trade a bit of clear for single target but this isnt the case.

4. The remaining chain buff is currently bugged. I have done testing and with my current level arc that has 5 chains + 6 chains from chain support + 1 chain from tree, I should have 12 chains. With 10% increased damage from each remaining chain and the 50% less damage from chain support one would expect 70% increased damage on the first hit, if my math is correct (I'm not fully solid on the PoE math and how the support vs skill mods work, correct me if I'm wrong). However, upon my testing I have found that the first arc hit does 50% less damage compared to the skill without chain support, I believe the skill is bugged for this reason.

5. Targeting needs work

Arc will often miss targets and hit the ground or go past targets entirely, it seems there is no autotargeting at all. Additionally, when compared to spark, arc cannot be shot through doors since line of sight is needed and, while spark can kill enemies off screen via the projectiles going there and bouncing around, arc cannot even reach the edges of the screen.

There are so many drawbacks to playing arc, it's deliberately handicapping oneself compared to playing spark. I miss Enki's Arc witch from PoE1 :/

At the very least increase the chain speed
