Well, if DDO isn't going to scratch my hardcore itch, I'll find other games that do.
I started playing 4 years ago, a month before HC3.
SC servers are a filler for when you don't know anything better to do.
There's no fun left in SC, repeating the same old quests with all farmed out gear (not complainging about that, because it was a lot of work and time investment getting there) on mostly solo r1.
I bought the christmas bundle (3 full blown expansions ultimate tier for less than 27€) of Elder Scrolls Online and after completing the HC goals now in HC9,
I TRed and am now left without motivation to continue, instead I'm enjoying the fresh new content on ESO, been logging in for 5 days straight now.
One hand: Fresh new shiny
Other hand: Old and boring grind
Sometimes repeating the old and known can be fun,
and if I hadn't completed the goals I'd probably still be grinding in HC9 for levels and rxp, because it's winter.
Ultimately not having a HC season in 2024 will drive me to play other games long term, to fill the boredom void, 7 races away from being done with the grind. New content will pull me back for a while, but I like PvP in MMORPGs and HC of "easy" content, because SC is just a filler.
For me, the ultimate motivation to play this game is a HC season.
I remember more than once, I was about to quit playing, then a HC season happened, and I continued playing DDO, even subscribing.
