I feel like these threads are always knee jerk overreactions. IIRC there was talk at the start of this version about SO being dead because ACGs had been nerfed. And about how carrier were useless because of skill changes (they weren't). Or about how low tech is left behind. Or about how Automated Ships was useless. Etc etc. No one's had a chance to play very much with EWM at 30%, its way too early to say its now useless. Maybe 30% is the wrong number and some other is better, but no one knows yet.
SO not being built in doesn't mean its not going to be used, just that its going to take OP instead of being a massive free hullmod. You can still build in other hullmods and have OP for the build, and the PPT for SO ships is still extremely long with stacked skills.
Even at 15% for half flux, this combined with Wolfpack is still a 35% damage boost for energy frigates: thats extremely large. Energy frigates are going to be fine, just not as dominant as they were.
