Nostalrius Begins - Quality wow vanilla realm (1.12)

Will this be possible to do on the server? Just like you could on retail, before it got fixed in late TBC /early Wotlk.
This was really really nice, not for abusing anything. But damn I spent many hours inbetween bg queues climbing stuff It was hilarious surprisingly funny.

I sure hope so, wanna explore the world all over again.

An example

Ive been wandering this also, learnt how to in WSG from a twink guild, and used it when the horde were abusing it themselves, might not be agreed on by all though.

There was a thread about this here on these forums long ago.
I recall something about a patch in vanilla that massively nerfed the old wall climbing potential. (ala Noggaholic videos)
However that video is BC so I can't compare.
I think the devs even responded in that old thread, so... try to find it again.

This is probably the thread you're talking about:

For the lazy ones:

"The 1.12 client had some glitches that allow players to reach some specific areas using wall jumping technics. Since these glitches are "Blizzlike", they cannot be considered as bug, and will be allowed on Nostalrius.
However, if someone abuses of it to get an advantage in battlegrounds for example, he may receive a warning, and appropriate sanctions may apply in the case of a repetition of the same offence." - Daemon
