Should just be ONE set of keys needed to access the boss, as it is with the peerless. Not everyone having to have a set. I finally did the pub 93 Zippy thing this past week with a couple of people, and realise that it will most like be the last time as getting people on at the same time who have done the keys is next to impossible. I have since done the pitt solo with two of my chars and gotten the keys again, and maybe at some point someone else will have them done when I am on, but I am not counting on it as most ppl have moved on from that to the pub 94 stuff so I have a feeling I will end up binning the keys due to lack of ability to get a group up.
I think if a char has done the 'whole' quest chain once then after that they should be able to go directly in with anyone who has a set of keys.
If I could yell in chat 'I have keys who wants to come' I have no doubt I would get some takers. The way it is now practically impossible.
As it is the whole quest chain to enter boss fights is the pitts. I don't know what bright spark decided this was the way to go, especially with most shards shedding population and getting smaller and smaller. It shouldn't take more than 2-3 hrs from the decision to 'do a boss' to the completion of the boss. That should include any prerequisites to get into that boss. The way it is now it can take 6-7 hours or more to complete the 'stuff' just to get in, by which time most people have logged out due to real life stuff. On larger shards with larger pop they can do it multiple times if it is a 2-3 hr turn around, and smaller shards would actually be able to complete stuff too. One set of keys means you are not deciding to do a boss then finding only 2 of the 5 players you want to do it with have keys, then you know you have to spend another 3-4 hours assisting them to get them by which time you have to log anyways. It is just a GRIND. I am certainly over it.
Quest chains are only good for 'one off' events. Talk about being bored to death having to do it each and every time. I means seriously : 10 water eles, 10 sea serps, 10 deep sea serps, 10 krakens over and over and over and over and over...................... seriously? Do you have any idea how damn boring that is? Not to mention that most of us can one hit kill a water ele or serp so if a bunch of you are attempting it you all have to power down and punch the damn things so that everyone can get a punch in before they die or else you might have to dregde up like 50 of em. BORING.
As I said above, It shouldn't take more than 2-3 hrs from the decision to 'do a boss' to the completion of the boss. Otherwise you cater only to the high pop shards, and LARGE guilds and destroy the game for everyone else. Which is pretty much what is currently happening on all small shards.
