We don't want information resurfacing that may be out of date. That can confuse players and also have us chasing things that may no longer exist. For example, let's say there is a two year untouched old thread about the balance of a dungeon boss. Going into the thread and noting the current balance doesn't make sense there. You are better off making a new thread.
@Destai I see your point raised here. I will check in with the team, but I'm willing to bet it's because of how the thread was framed. It started in 2020 and was framed regarding a potential new class for 2021, which did not happen. I do think it's fair to start a new thread for those who want to speculate a potential new class in general.
Also just want to note that one of the recent comments was from a user who did make an updated thread in June of this year on the new class topic.
if a thread is over a year old, why not just delete it instead of waiting til someone posts in it which is bound to happen sooner or later. Alot of posts come back as the first result when you search up somthing for ESO on Google. I have had 2 issues i searched send me here only to post and have it deleted the next day lol
