Do I really want to raise the dead?
In this case I would argue it is warranted; great suggestion!

The reason for the "no necro" rule isn't that a thread is automatically irrelevant after time passes. Though, in some cases, yeah, the conversation applies to an older version of the game and that can be confusing. But a big part of it is that it may not be immediately obvious to someone that some of the posts are super old, and someone might respond to them expecting to get into a conversation, etc. It's just... well, it can get confusing.
I'd say the better way to go for something like this is to make the same suggestion again! The thread is more likely to get some activity, too, since for a necro'ed thread, the people that *are* aware it's a necro are less likely to post in it even in response to the more recent posts.
