I run E Von 3 from 3 to 5 times a day on characters that could easily solo it. However I always open a pug and welcome all players that have more than 320 hp. I don't know why 320 is my cutoff btw. I see strong and very weak players join my pugs. Since the quest is quick and the xp so great I don't judge people unless they are rude or disruptive. I have not kicked/ discriminated against players that have died even in the prequest (shocking but true).
Halving the xp really reduces the incentive for me to run the quest especially with players that are likely to die or can barely contribute. I know this is the intention but this change is more than just xp. It causes the game to be just one more bit unfriendly and unwelcome. When the xp was abundant, I went out of my way to be generous. And this game doesn't need any more reasons to be unfriendly or unwelcome. Also since this quest was so universally popular it became a mixing point between veteran and newer players. It was a mixer like the old shroud and it let weaker characters see some real min max builds in action and it let vets see experimental builds and see typical players in action. The game as it stands now has stratified quite a bit. There is a huge difference between a multi-life fully geared monkcher and a sword and board melee with average gear. And for casters a similar divide is growing. I see casters who can kill a mob (continuously) every 2 sec to some that need a full 10 seconds.
I genuinely wonder if the devs and turbine staff realize that the after effects of some decisions are greater than what is immediately apparent. Another big one is the placement of quest entrances that require an absurd long run to get to. Probably the worst decision was to punish larger guilds for having more casual members and as result the great kickout of a lot fun players whose only crime was that they played only once a week. Finally, the lack of a varied raid scene took a big bite out of the life of the game. I remember when people would gather for raids and do small talk during the easier ones then when done, would break for questing groups. I genuinely miss those times.
For the devs and Turbine in general, small things can have big unforeseen consequences. I hope the player council can help you avoid some of the larger losses in the game.
