When targeting anything aggressive, (red names), Chain Lightning shouldn’t bounce to anything neutral, (yellow names).
This is really annoying since it starts unnecessary combat and possibly uses a bounce that could be used on other aggressive mobs.
In my opinion it should work like this:
If an aggressive mob is targeted, Chain Lightning should bounce to other aggressive mobs only.
If a neutral mob is targeted, Chain Lightning should bounce to other neutral mobs and aggressive mobs.
