"Last i checked you still had to actually tame the thing all while avoiding lots of spawn."
There's no spawn after the Vanguards are defeated and everything is cleaned up. A lot of times the Vanguard is killed in between spawn times, so there's not even anything to clean up afterwards.
"if i just had to defeat a vanguard no problem i could dust them problem is they keep teleporting back and summoning large amounts of spawn way to much for one person to handle"
I, and many others, have been soloing the Vanguards, and that includes dealing with the spawn. They can be taken down even faster with 1 or 2 others working together as a team. Maybe you should try some different tactics.
"if your dealing with lots of people which is what it really would take to do anything significant"
Again, maybe you should think about some different tactics and get 1 or 2 people to go with you and work as a team.
"some moron will probably kill the horse there goes your "prize"'
That happens, but there are 3 cities that all spawn at the same time, and I can tell you for certain that at least 1 is empty every time the spawn occurs.
"Stupid change revert it back...."
It was supposed to be this way to begin with. That WAS the way it was orginally announced as how it was going to happen once this part of the invasion was turned on. The fact that they could be dismounted was not intended to be the way to obtain the mounts.
All that aside, I solo'd, and afterwards tamed, 3 of the horses myself just today. It took a little while, but that just shows you that it can be done with perseverence and sound tactics.
