While I am grateful for the chance to keep T5 ships relevant in the meta game with their inclusion in the x-upgrade system, the cost of getting a ship to that level far outweighs their practical benefits.
Let's take a ship, say the Tempest class Heavy Patrol Escort. For this example I am going assume 3 things: 1) all items are at regular cost without sales, 2) the player has not reached tier 6 in reputation, so no free fleet modules, 3) the necessary tokens are purchased at their singular price.
First the c-store ship itself weighs in at 2500 zen, or ~€25
Second we want to bring it to fleet level, and a module costs 500z
Third we need a T5-u token, that's 700z
And finally we need the x-upgrade at 1000z
That's 4700z, nearly double the initial cost of the ship in question.
Now I understand sales can mitigate the cost, and no one would really buy anything outside of a sale, but it still seems unfair that a T5-U-X require such a cost.
My solution would be to humbly suggest the T5U tokens be dropped. They had their use when T6 ships were released, but that was 6 years ago. It's high time to drop the system and make all T5 ships auto upgrade.
