Addressing some of your points:Here's the problem with some of your logic:
1-Try an alliance friendly campaign. Awesome advice, except for the ridiculous queue times. I spent 3 hour waiting to get into Azura's on AD during an off-peak time. Nobodys got time for that nonsense.
2-Roll a NB. Yeah, F-off.
3-Use pots/stealth. Does you absolutely no good against 15 enemies stacked at the door. The moment you attempt to open the door...instadeath.
4-Go with a group. This is probably the only advice worth a damn I've read in here. The problem is that it's simply not always feasible to find a group in a timely fashion.
5-Try other entrances. This is just poorly thought out. The campaigns you can get into, as previously mentioned, are typically that way because they're dominated by another faction. You're not riding around that lake in 10 minutes in an enemy dominated campaign. No way, no how. Besides that, the secondary entrance is probably being camped as well, leaving only the main entrance for the dominante alliance. I'm guessing that I don't have to explain the complication with that.
I find the argument that they're trying to encourage PvP partially accurate, but flawed. What they promote through allowing this is complete imbalance within the campaigns. It's no different than it was prior to IC: Campaigns so dominated by a single faction that they become intolerable for other faction members to the point where actual PvP declines and they become massive defacto PvE grindspots. This is how Azura's has always been. There are days where you almost can't find an enemy player.
Personally, I think most of you saying that you've never had an issue, or that you just beat down overwhelming numbers of players, are FOS, but at the end of the day it doesn't matter because it is what it is, and unless Zeni creates some form of direct access, people are just going to throw in the towel.
