I started experiencing something similar with the horde gunship taxi which takes you to the dragon isles. As you attempt to cross the small platform and board the ship, your character turns 90 degrees to the left and often you can’t cancel movement fast enough, which results in falling off the tower.
The only way to safely board on foot is to tap the forward button repeatedly.
I can confirm that I have the same problems when I try to go on/get out moving platforms like ICC and Gnomeregan elevators, the boat to Northrend, the tram between SW and IF etc. etc.
Things worked fine before that 10.0.5 patch, now everything is f’ed, on both computers I’m using (and I even deleted the WTF, Cache and Interface folders, so it’s definitely not a hardware problem on my end).
It’s extremely annoyin’, I regret I subscribed (on all my 3 accounts even) for 3 months, if Blizz won’t fix this basic functionality problem in the future I won’t invest a single cent in this great-but-full-of-bugs game.
Still can’t believe after 2WEEKS this is still happening!
Took the Deeprun Tram just now and my toon did a 90 degree on me running left and coming off the tram and fell right into the track-pit.
Oh well fingers crossed for maintenance tonight.
