Power creep is unavoidable in a game like STO. New mechanics are introduced; the community gradually comes to establish knowledge of a meta; certain stats are just inherently imbalanced against others. Frankly, I'm fine with power creep overall - it means you're dealing with a product and a playerbase that has fully maturated.
What I am NOT okay with - and it is a behavior that Cryptic is wildly guilty of - is leaving older ships, weapons, etc. in a non-competitive state once the tide has rolled out. No, PvP isn't a big deal in STO, and yeah, the endgame is kind of a joke. But, IMO, that's all the more reason that it's completely unacceptable to leave dozens upon dozens of ships in a state of deficiency - you're asking people to essentially make their own content, and for a lot of us, that boils down to min-maxing builds and trying to throw big numbers. Broken or badly-designed starships don't fit into that equation.
So many of the ships - on the C-store, on the fleet vendor, or from lockboxes - are either outright garbage or a hair's breadth from being in that state. Worse, a large portion of these are still 'for sale' in one way or another. Cryptic is literally asking the same money for a Gegarin as they are a Europa - and people (many of them too new to understand the difference [especially since the game does such an outright horrid job explaining how nearly all its systems function]) throw hundreds or even thousands of dollars after vessels that are woefully out of date, with no hope of them ever being brought closer to par.
I just think it's silly that more of an effort isn't made to occasionally do a pass over on some of these older products in order to clean them up a bit, or to reconcile them with ships that would be released in the present day. Cryptic doesn't have to spend hundreds of hours re-texturing models, nor do they have to tackle the massive pile of antiquated boats all at once - just pick one or two dated ships a month, move a few consoles around, check the boffs, add or exchange a mechanic or two, and call it good.
Not only is this a low-cost means to regenerate interest in older ships (since, very obviously, the bulk of design time is spent on the models [if the changes done to the ships in the anniversary bundle are proof of anything, it's that stat alterations can apparently be made on the fly]), but it's also simply a good way to keep people playing (since the more ships were tinkered with, the fewer that people could just shrug and write off as 'useless trash'). Frankly, I don't see a downside here - there's financial motive to act on these derelicts, and Cryptic themselves has now shown that such changes can essentially be done while firing from the hip. It's time to stop letting so many of the spaceframes in STO rot in disuse.
