I got to ask.. Has anyone done the 'leader killing' acheivement since the ability to fly in the regular sections of Azeroth came out? I'm just curious. I mean it would make getting to MOST of the leaders a lot easier. (Ironforge/Undercity being exceptions)
Tried, it's actually EASIER to do it against the Alliance now. Horde side has WAY too much defensive power.
Garrosh's entrance is a bottleneck with wall, forcing you to either split your forces to cover the two ways (Which ironically is still the front door) or get slammed in the ass. The Kor'Kon (or whatever they're called now) are still overpowered. And worse? It's in the front of the city with the banks, the AH and other high traffic areas of the city, meaning local defenders will be able to respond in seconds.
Undercity's cramped caverns and tight tunnels are as much a bane now, as they were when you couldn't fly, so Sylvannus is still well covered.
Thunderbluff is a trap. High above the ground with a boss that pushes people obscene distances. Inta-raid wipes.
One the other hand, Ironforge has a tunnel in which the Horde can now use to stage attacks, instead of just getting lodged into the throne room.
Stormwind has an open air PARK right beside the throne room.
Gnomeregan is not that big a threat, and it's so out of the way from high end players that it's easy to crush.
The only two that haven't changed is due to Blizzard forgetting to update the Burning Crusade content.
On Feathermoon the regicide has actually slowed to a crawl. Most Horde has already got the achievements, and the Alliance (being the disorganized slobs that we are) can't seem to actually get anywhere. Not to mention that the Alliance have a visibly harder time of it now.
