All do you respect, you can admit this patch took so long. I was wondering if there is a plan to make some chanings before Misty Mountains release like siege and power spell menu or it depends on requests of team members and players. I know Narya, Axe of Doriath, Woodsmen of Anduin, Guards of Orthanc, Ancient Might of Galadriel but is there any addition or accepted idea? There is not full list, this remains an enigma. I just want to know how it works.
May you pardon me, but I didn't understand very well what you're trying to ask.
There will never be a complete and definitive list of changes that could cover all possible plans up to the release of the Misty Mountains. It would be objectively hard to do that: the Edain Team could come up with overhauls and changes in any moment. What the Edain Team does do, instead, is to release specific articles concerning the changes which are to be, with the guarantee that those defined elements will be implemented. There's not another feasible way other than opting for periodic updates. This is the custom they have followed with constancy so far.
The 4.5 patch is indeed taking quite a lot of time, but that's justified by the considerable magnitude of the update itself and by Ealendril's departure, which doesn't make things easier for sure. Patience is the only virtue I could advise you adopt
Just a few words about the concepts I worked on in conjunction with the Edain Community: apart from a couple of remarks by some developers, those concepts have never been rejected nor accepted by the Edain Team. That is, we didn't receive yet a final response. Once the main priorities are successfully sorted out, I hope we will know, mirroring Saruman's words, where our doom will be decided. Before official answers, those proposals shouldn't be regarded as actual future content.
