Think about it… as far as I know there isn’t any ladder climbing in the entire game. Maybe some cutscene? But I never seen anyone actually get into a ladder climbing pose or even animation. Weird. I mean the fantasy setting with lots of old places, abandoned houses, roofs, ought to have ladders literally everywhere. We do have some, but you click them and just fly up in a ridiculous manner.
I wonder what stopped them from doing it. My best guess would be getting in combat while on a ladder, then what? Do you autodismount, fall and die, can you use any abilities while climbing? Can’t get those animations to match. Just too much work and effort, they decided to not even touch it?
I remember few ladders in game, but you are not climbing them, you just click on them and your character jumps at the top of it There is quest in Hyjal where you have to throw baby bears on trampoline, there are ladder like that
What this lad-der you talk bout?
Me warrior, me need get up high, me jump!
Seriously, as mentioned there are several ladders ingame, but all of them involve jumping to the top rather than having an animation for the ladders, which is kind of lazy, but then again, we don’t have to sit through a long ladder climbing animation every time we use one =)
You mean like the ladders on the boats in boralus?
You just yeet up them, probably were just too lazy to design an animation for it, which would probably look stupid with all the huge races we have though?
There have been ropes where you climb though, so I guess they do not have actual ladder worthy animation and here they might believe that players just want up there without much roleplay.
Especially during launch of BfA - for example, where alliance players managed to drop into water a lot. The board players use now was added later.
