As worded, I think it would. Every bit of the map geometry and audiovisual content in WoW is client-side. Server only handles chat (via hybrid-ircd, I think?), and via the main daemon (which seems like it might have been Lua-based at one point, or at least link into it like the client does), state coordination including item looting, and creep behaviour. Creep/boss behaviour and looting have been studied closely enough by tactically-minded players to be effectively black-box reverse-engineered, and fully reimplementable to a high degree of fidelity and precision. (I'm not going to do it, I quit a while ago, but I did make a pretty popular addon, and did look into things a bit.)
