I think t4 ships should have some reason for them to be used besides a transition to t5. t1 and t2 serve as a beginner’s point, t3 allows you to have the best ships for 4-9 pve, but t4 has no use. I have no reason to upgrade the modules, and the ships are borderline useless for pve. They only are there to be leveled up before t5, and I wonder if there could be some t4 only missions that maybe would make these ships better utilized?
Something like sec-conquest or spec-ops but only t4 ships allowed would be preferable, so you can not have to work about r15 premiums making you obsolete, and also enjoy the ships in a field where they have maximum usefulness.
Another option could be to give t4 ships something that incentivizes people to use them, maybe credit boosts periodically, or something else would be fine… I just want to feel like these ships have a competitive aspect beyond pvp only.
