So you don't know what loot-scoot is, then? Is that what you're saying? Because anyone who played on the US servers between about November 2004 and November 2005 should. Y'know, when loot lag stuck you in the crouching position for 10+ minutes?
I take it you don't know what "staged content release" means? I.e. you don't release all the raids at once - first MC/Ony, then BWL, then AQ etc.
If you're claiming something is the "only logical solution", and you can't answer basic questions like those, then you are not being logical.
They don't have the proper back-ends for ANY Vanilla builds (except possibly 1.12 I believe). This is what you don't seem to get. The Vanilla builds people have re-creations of WoW, from the CLIENT-SIDE patches, with limited information about what was going on server-side (if this isn't correct, hopefully an emulation expert can correct me), because to obtain the server-side stuff, you'd need to have cloned or hacked a WoW server (which may have happened a couple of times, but it'll only be for very specific patches if so).
The idea that they should just let well-known exploits go live, then ban people after the fact isn't even worth arguing with.
