Why would you even comment in this thread when you obviously dont have a guild?
people in small guilds that actually like to play with each other should not have an obstacle like this to surpass.
I have a small guild, with 4 other RL friends, and i'm also part of a big guild. what if i want to do the content with my small guild? my only hope is that the combining of guild efforts can be done in such a way that it doesnt require for every guild to have the upgrades maxed.
His input was useful, he pointed that out that the sky isn't falling, like every small guild is trying to make it seem like. You can unlock the content if you want to. Eventually you will be able to start it if you want to. Literally nothing is stopping you other than yourself.
The ability for you to complete the content doesn't change by the AoW level 5 pre-req, if they had not even had the pre-req the body count and difficulty of the mission would have been just the same.
The content isn't even out yet, no one has tried it yet, there is no reason to pass harsh judgement against it until it is tried. By the way 73 gold is actually pretty easy for one person to make in a week with fairly casual play and without playing the TP. A week before the semester started I was able to buy a full t3 cultural set (and a set of exotic weapons to go with it) starting from scratch only playing 3 hours a night, basically of just fractals and CoF exp on my necro. There is absolutely no reason why a group of people can't pool together a similar sum in less time.
If it turns out that guild mission isn't for your guild you at least have it unlocked. You could then charge other guilds that don't have it unlocked to start the event, either gold (which your guild could put back into either gaining more influence to open something else, or even a commander book for the guild) or just have them represent your guild while they do that content, re-earning the influence and possibly recruiting new members.
There are plenty of solutions to this problem, and it's a soft gate at worst, a small speed bump at best.
