Wormholes
Elimination of the old clone grades
Thera
T3 destroyers
Upgraded bookmark system
I would say that most of the updates are either MEH or positive for me. CCP has a really hard time balancing highsec ganking mechanics, but they are trying to maintain balance. At least they are trying.
I like the T3 Strategic Cruisers, having the ability to customize them with various Sub-Systems creating different fitting slots made them especially great as a ‘Nomadic’ ship.
However they didn’t really excel at that until later when CCP updated them to include a Sub-System Bay and interchangeable Rigs.
