Objectively wrong.
This only happened to 2 skills: Battlecruisers and Destroyers. That’s it.
Also incorrect. The learning skills were removed. New players were expected to train those. Not Battlecruisers. That’s millions of SP eliminated. Destroyers SP wasn’t enough to offset the learning skills. Additionally, all characters’ attributes were increased speeding up SP gain, particularly for newbies who didn’t have to train learning skills anymore. That makes your narrative even more incorrect.
