Arc suggestions

I've been playing Arc this patch and here are my impressions, the ability itself looks good and feels good to cast and play around it, but i think it needs some buffs. I've been thinking about for example, making it able to chain with the player so then it can be turned into a very viable option for single target as well, or making it able to chain more than one time for every target, i mean, if you have for example a 5 mob pack and you arc chains 7 times, make it prioritize the first 5 chains one for each targer, but the last 2 to target random enemies in that same pack, and place the player as the last priority only if 1 target is alive. Because it feels kinda weird that when you cast it on a 2 or 3 mob pack, to watch how it just go away once it chain on all the targets... I hope it makes sense. I'd like to know how would you see those changes if you're an arc player. Cheers!
