Realm Best Titles: There are extremely limited titles that are held by the players who hold the best clear time for a given dungeon on a given server. Since those Challenge dungeons will no longer be available in Warlords of Draenor, their respective titles are also being permanently removed. There will be new Challenge dungeons in the upcoming Warlords season, and new titles for which to contend, however.
Does this mean I will lose my title(s)? If so ill make another post asking for that to not be the case. I worked hard for some of my times and it is will be meaningless with nothing to show for it if they're removed so why should I bother doing times anymore? Idc that much about them but I had planned to have them all before CMs were removed.
EDIT:
@Sensashuns Completely removed. Those titles reflect being #1 while the CMs are active. When they aren't available, the title has no meaning

we must rally this is unacceptable....darkmaster is perhaps coolest title in game you can't just go removing it willy nilly!
Yes these titles will be from when they are active but people have had months in advance that CMs were going away, if they wanted to compete for times they could! This specially unfair for region best times, top 10 or so should keep the titles. The hours it took to obtain them...the nightmare of SH.....

Thanks for all the feedback, and I understand that while much of the news was positive, most of the people who have worked tremendously hard for the realm-best titles are justifiably upset that they will not be permanent.
The realm-best titles were added with little fanfare in Patch 5.4. It's possible that they were a flawed idea in their conception, but the hope was to foster a bit of competition within individual servers, and to encourage people who had long since finished up their Gold medal collection to revisit the dungeons and try to dethrone the current champs. The titles were by nature transitory, where any day you might log in and discover that someone had beaten your time, and that you'd lost the title. We added Feats of Strength, which were permanent, to recognize and commemorate the fact that you held the title for a time. These Feats of Strength remain among the rarest in the game.
서버칭호들은 자연스럽게 사라질 수 있습니다, 어느 날 당신이 로그인하고 다른 사람이 당신의 기록을 깼다는걸 발견합니다, 그리고 당신은 칭호를 잃게 되는 것이죠. 개발진은 위업을 추가했습니다, 이 위업은 영구적인 것입니다, 위업은 당신이 서버1위칭호를 가지고 있었다는걸 나타내주고 기록을 갱신했다는걸 기념할 수 있습니다. 이 위업은 게임 안에서 굉장히 희귀한 업적으로 남게 될 것입니다
If we'd wanted to add a fixed Platinum Medal tier with additional rewards, we could have done that, but the point was to encourage friendly competition against people you see standing around town on a regular basis. We're also aware that while essentially any class composition can get all Golds, balance breaks down at the extreme high end of the spectrum, and we wouldn't want to set a formal benchmark that some groups couldn't reach even with expert play.
만약 개발진이 플래티넘 메달 등급을 새로운 보상을 더해 추가하길 원한다고 가정해보면, 우리는 그렇게 할 수 있지만, 그러나 기본적으로 중요한 것은 대도시에서 만날 수 있는 사람들간에 긍정적인 경쟁을 독려하는 것입니다. 개발진들은 또한 필수적인 직업으로 구성된 파티가 금메달을 따는 동안, 이게 다듬어질수록 (조합)밸런스는 참여가능한범위 안에서 굉장히 심각하게 붕괴될 것임을 주시하고 있어야 합니다, 그리고 개발진들은 어떠한 직업간의 조합이 그들이 정말 뛰어난 실력을 가지고 있더라도 기록갱신에 도달하지 못하게 되는 것을 원치 않았습니다
Looking ahead to Warlords, we were left with the open question of how to handle the realm-best titles once the current set of Challenge Modes ceased to be available. By default, if we kept the titles as-is, the final players who held them on the day the servers went down for patch 6.0 maintenance would have kept them. Unless they ever transferred servers. Or unless their realm got connected with another realm with faster record times. This is because by definition, the titles are tied to a specific realm, and were always meant to be. Keeping the titles around with that level of inconsistency and uncertainty was not an acceptable outcome in our eyes.
드레노어의 전쟁군주를 놓고 보면, 현재의 도전모드에 서버1위칭호를 따게 되면 도전이 중단되게 되었고 다시 활성화되게 만들 수 있을 것인가에 관한 질문이 남게 됩니다. 자연스럽게, 만약 우리가 지금처럼, 6.0 패치가 적용되어 서버가 닫히기 전에 그 칭호를 마지막까지 가지고 있던 유저들에게 칭호를 획득하도록 한다면. 그들이 서버이전을 하지 않았다거나. 아니면 그 팀이 연합서버로 구성되어 이어진 서버에서 더 빠른 기록을 가지고 있다면. 이건 당연히도, 그 칭호가 특정서버에 묶여있어야 할 것입니다, 그리고 그래야 하구요. 그런 모순된 경우에 서버1위칭호를 유지하는 경우와 그런 불확실성때문에 우리 개발진의 눈에는 영구칭호가 허용할 수 없게 비춰진 것입니다
We considered an alternate option of letting all players who have the Feat of Strength for ever holding a best time, however briefly, permanently keep the title associated with that dungeon. The major downside there, as I noted on Twitter, would be the precedent it would have set going into the next Challenge Mode season. Should the first group on a server to get a Gold Medal in the Shadowmoon Burial Grounds (one of our upcoming dungeons), the first week of the expansion, earn a permanent title, while another group a few weeks later that clears the dungeon four minutes faster (but not a new record at the time) does not get that same reward because they waited too long to stake their claim? We also do not want to encourage groups to seek out less competitive servers just to grab best times and thus permanent titles.
(만약)드군에서 새롭게 공개될 던전에서 금메달을 획득한 서버내 첫 번째 팀은, 확팩의 첫 번째 주 동안, 영구적인 칭호를 가지게 되고, 다른 팀이 몇 주 후에 4분 정도 빠르게 던전을 클리어하는 동안(그러나 그 시간동안 새로운 기록갱신은 아닌) 그들은 너무 오래 기록을 가지고 있었기 때문에 똑같은 보상을 받지 않아야 할까요? 개발진은 또한 영구적인 칭호와 서버1위칭호를 위해 덜 경쟁적인 서버들을 찾는 현상이 나타나길 바라지 않습니다
The groups that set records this time around will surely be top contenders in the Challenge Mode season, and you do have a unique Feat of Strength to record your accomplishment in Mists. That said, we clearly should have settled these questions sooner, so as to better set expectations.
기록갱신을 했던 팀들은 도전모드 시즌 동안 최고의 경쟁을 펼쳤다는건 부정할 수 없는 사실입니다. 그리고 판다에서 이룩한 기록갱신에 관련된 희귀한 업적 또한 가지고 있구요. 그게 말해주는건, 이런 질문에 대해 개발진들이 빠르고 명확하게 밝혀줘야 한다는 것입니다, 그것을 통해 기대치를 명확하게 설정할 수 있게 될 것입니다
