Are the current 4 mans going away when the new dungeons come out?

[Shelly]

Also, is this going to be a repeated pattern for every time a lot of new dungeons come out as well as hongmoon levels being raised? e-e

And if it is not going away... will the 4 man yeti, necro, and lair inevitably go away at some point.? e-e

I miss 4man poh and bsh. :C

No, they're staying. KR still has all the 4-man Silverfrost Purples.
