Legion release date announced, but also last chance to collect:
World of Warcraft: Legion now has an official release date: 30 August, bringing with it many new mounts! But it's also likely that at least three current mounts will be retired (or semi-retired) well before this date, with the pre-expansion patch. If the release schedule is consistent with previous expansions then this will be about a month before, i.e. the end of July, but it could be sooner, or later. The mounts likely to be affected are:
The Grove Warden, obtained from a quest chain that begins with an object dropped when killing Heroic Archimonde (100% chance if you are eligible). This object is supposed to be removed in the pre-Legion patch. If you're worried about getting this one, check out the wonderful folks at Friendship Moose.
The Challenger's War Yeti, earned by completing Challenge Warlord: Silver. If this challenge dungeon reward is consistent with those of Pandaria then the achievement will be discontinued with 7.0 and you will no longer be able to earn this mount.
The Brawler's Burly Mushan Beast is probably not going away for good but it may be gone for a while, as the Brawler's Guild is reported to be going on hiatus in Legion.
The Dread Raven won't vanish entirely, but will become more difficult and expensive to obtain. Currently the only easy way of obtaining it is by purchasing the Warlords of Draenor Digitial Deluxe Items Bundle in the Battle.net Shop (US / EU), but this was announced as being removed from sale with the pre-expansion patch. The Dread Raven will still be obtainable if you manage to find an unused (and increasingly rare) Warlords of Draenor Collector's Edition.
