There have been too many times where I have encountered guild groups in the Dungeon Finder and been subject to the humiliation of their control. Often the guild group will take advantage of the fact that they have the three votes it takes to vote any one group member out. Not only this, but they will also take advantage of the extra loot rolls they have in order to roll for items that are not useful to them, but are useful to their guildmates, effectively doubling their guildmate's chance at winning the loot over you. I really love this game and I have been playing since Burning Crusade. However, this guild control over the dungeon finder is proving to be too stressful for a video game environment, which I believe should (ideally) be a time that you can unwind and relax a bit. Time and time again, these encounters have broken my spirit, as well as for other players that I know.
My constructive suggestion to combat the overwhelming power and influence guild groups get to vote other members of the group out is to require a group of three guildies to require one extra vote in the kicking process. I do not have a solution for a guild group of four, but if anyone can think of something, please post your ideas! As for needing on gear you don't need in order to trade to a guildy... I think that the new raid finder loot system is most effective in stopping that sort of shenanigans. I'm sure there are some that prefer the old system, but I believe this new system to be more foolproof, and I hope that this is Blizzard's thought as well.
I encourage anyone else to respectfully comment and post evidence of their stresses regarding this matter as well. I will be posting my evidence from my most recent issue as well as any in the future as soon as my forum account can access that feature. Hopefully someone of influence will read this thread and bring these problems to the forefront so that they can be tackled accordingly. Thank you for your time and patience reading this.
