Mage PvP Question

[Lissa]

What makes this so exploitish is that (last I checked) you can capture the workshops while standing on top of them. So not only can you harrass any of the opposing team on the ground with almost impunity but unless they counter you with the same amount of players sitting inside the workshop the people on the roof will eventually take the workshop without having to fight for it. It's cheese at it's worst and for most servers that aren't very balanced for Alliance/Horde players it means that the higher player count side can sacrifice the players to just sit up on the workshops.

You do realize that destroying a workshop (outside the fortress) with seige engines will cause it to swap sides right? Doesn't matter how many people are standing on top of it or standing inside of it, if the workships outside of the fortress are destroyed, they switch sides.
