Alternative suggestions for meeting with Blizz

Here are some alternative friendly suggestions for consideration when meeting with Blizz. These are some counter arguments that I haven't seen a lot elsewhere.
Blizzard have run the data, the business case doesn't stack up
Blizzard had capacity and scaling predictions for Vanilla in 05/06 - how did these work out?
Did they plan for opening new servers month by month to accommodate off-the-scale demand? Did they predict they would end up with MILLIONS of subscribers in the first year?
Vanilla WoW is beguiling gaming MAGIC, never created before or since. Blizzard underestimated the power of Vanilla then, is it possible they underestimate it again now?
It won't be popular
It has been a decade since Vanilla launched, and over those years I have encouraged new players to try WoW of various ages and maturity. Players I introduced in Vanilla/BC played for years, but players I introduced in Cata barely played for weeks.
The market for Vanilla... yes there are veterans who would come back but there is an entire new generation of players who have never had the chance to enjoy Vanilla WoW, to be hooked by its addictive magic. What will happen when these first timers play Vanilla...? The whole journey starts again! Imagine seeing population figures growing in the first year on a classic realm... Do you think new graphics, garrisons or AOE looting makes a difference compared to addictive magic formula of original WoW, the world, the community, the environments, the ADVENTURE?!
People won't pay
Some argue that players only played private servers because they were free. I say lots of people don't play private servers because they are free. Most people want to pay fair value, they don't want to participate in unauthorised, unsanctioned ventures because it may be against Blizzard TOS, it may even be technically illegal. Aside from ethical questions, or user agreements, it also is off-putting to invest time in a character that could disappear at any moment.
How many people would be enticed by an authorised official service but won't play on private realms. Is it possible the number of people who be willing to pay to try a legitimate Vanilla WoW server actually outweighs the number of people willing to try a private server?
Keep the game moving forward
Imagine that Blizz launches a vanilla realm to test out demand. It turns out to be popular, more popular than expected, a new generation of WoW begins, hundreds of thousands (or millions?) of players start from the beginning, and we have a few years of fun, levelling up, gearing up, clearing raids, experiencing Blackwing Lair and Ahn'Qiraj and the great war effort. Many players experiencing legendary WoW events they missed first time around, they will LOVE it!
But once we have cleared everything it makes sense there would need to be some progression - so do we move to TBC? then to WOTLK?
What about... a new expansion? An alternative path of WoW...? You could keep concepts that made expansions great, but avoid the mistakes of the past! Now there is an interesting idea, no? A new expansion bringing the excitement back like The Burning Crusade, but with new zones, new bosses, never seen before, but without all the big mistakes of the past.
This could be how Blizzard can "keep the game moving forward"...
Conclusion
Well these are my main points, thank you for reading
Ok maybe this last suggestion is slightly off the wall, but when you start to imagine the possibilities its pretty exciting.
If you want more, I have added my own thoughts on why old WoW was so good below. Most of these points I have seen elsewhere though, I just wanted to post them somewhere. But I put them in a separate post because it is more repetition than above.
For the Alliance!
For the Horde!
For Vanilla WoW!
