at the beginning I would like to state that:
a) I am not experience WAR / RvR player
b) I have deep respect for those who decide to lead PUGs because of the patience and hard work it requires
Now I'd like to start a discussion, or make my suggestion.
Would you please take into consideration a different strategy while creating a warband?
I just crashed from order attack at Praag keep, thanks RNJ for taking me from this hell. There were 2 public warbands, random people with zero to little communication between them (not leaders, players, parties). We managed to attack lord, one WB was supposed to defend ground floor entrance, the second to slay the lord. It reset 5 times, half of the warband was somewhere else (fighting outside the keep for example). So we switched tasks, the other WB attacked lord. It reset at about 10%. Still, some of our WB players were somewhere else, not listening to commands. In the middle of third try I crashed, and I'm not coming back, so I don't know how it ended.
It's just a salty story, but wanted to show the reality of PUGs. It's not the first time it happened and I'm sure everybody have similar experience.
My suggestion isn't new, isn't original. I would propose for those who have mental toughness to lead PUG, to instead making an open warband, just shout at LFG what you need, and create proper parties where are healers, tanks, etc. After creating make sure everybody know they have to follow the leader and listen to commands. Make sure they know where to stand during a fight, and during keep lord assault.
That will make people think and consider themselves in a bigger reality, where they have to cooperate in group. First of all it will erase all complete randoms at WB who don't even know how to communicate - they will have to write a message to get invited. Secondly, it will function better, with proper amount of classes who support each other. There still will be overflow WBs, there still will be lord resets, but with this mentality, people will maybe finally start to improve at what they're doing, if we start to improve the standard of RvR. I would recommend to not be afraid of making people think, to have requirements.
That will also, I hope, end this frustration which causes other people to leave and never come back to RvR. We have to stop with this poor quality and demand thinking from players.
It's not equal to creating guilds, because they run with people who know each other and are more constant. I'm saying of creating warbands that consists of randoms, just in proper parties and with their conscious agreement to listen to a leader.
Probably didn't use all the arguments and forgot about something, feel free to point it.
Have faith in those dark days, may the Sigmar bless PUGs!

BTW image isn't mine, I just feel that this is how PUGs look like
