TF2 is blessed because the developers made a promise never to add a 10th class, so at the very least you can abandon the game in 2009 and come back in 2024 and it's somewhat recognisable
Compare this to games like R6S where the entire meta has been warped in just two years and you now need to BUY new classes to compete with everyone else who already has them
The only live-service developers I trust are ones who either pledge to only add cosmetic content or establish that the content pipeline will be limited and short in duration
As an exercise, chop everything past the first year off your favourite live-service game and you'll probably find that the game isn't that much worse - or, more likely, is actually better
