Probably... Tidalwake seems to be complaining about thunder being hard to play though. Sometimes having options is more important than hitting hard, and light definitely provides options given the himes he has. Dejnov gave more details on light himes that further expands the tactical options. I know very little about thunder, so I don't know whether it gets easier/more versatile with the right himes so I can't comment further (where are the thunder mains, Slashley you want to comment?)
Also, I didn't notice this until I reread the posts but:
Very important note about Eros AW - whenever she bursts, she can recast the affliction block, so on a fast light team, she can have it up pretty much all the time unless you're up against bosses that spam DoT every turn or something (but that also means your team will be super fast as a result.)
