Paralysis is overpowered.

[K]

There are plenty of cheap ways to kills SCs with less research and/or paths, and paralysis isn't even one the best ways so "no, I don't think it's overpowered."

In general, I think most people always declare anything that hurts SCs as "overpowered." Since I don't want SCs to become the only end-game tactic, I'm in the other camp. I think SCs should have a place in the game, but not the dominant position that people who invest heavily in them would like.
