Immortal teams aren't a thing on CN. Wait for the stat overhaul patch (I believe it will come with 3.0 but not 100% sure) in addition to Roshi will probably be the deathknell of the current water main/earth main healing teams.

I'm not too sure what the point is for nerf/buff threads since Oasis is a publisher, not a developer. I highly doubt they are able to perform game sweeping changes even if they wanted to; they are merely porting over the CN version over time. It's another reason why I think the cross server polling was done poorly - many players believed the poll meant they would either get cross server SWB or they wouldn't, not that the function would just be delayed. Every core game function that CN has we will eventually get (this includes the eventual cross server GNW).
