If you were directing this to my guild you would have a point.
However, If you ever run with truly casual players, they don't rush the dungeons. They are not there to maximize xp/minute or get loot. While it may be hard for you to understand why it takes so long to get renown, it really is a function of how you play the game.
1) If you run the quests slowly you may only run one dungeon in an evening. I run with experienced people that take time and I know when I group with these folks I will probably only get one quest in the whole night. There is a lot of chat before the quest and we sometimes wait for people to see if they log on. Then the quest itself takes longer.
2) If you run quests at lower difficulties you get less renown
3) If you run quests at lower levels you get less renown
4) If you are ftp and you are grinding for xp, you will run alot of quests @ ransack for certain levels getting only 10% xp per quest because there is nothing else to run. You won't get any renown.
Again I feel compelled to point out the double standard. We made this change to help casual players - and the casual players in large guilds were helped with a massive decay reduction. This person pointed out the difficulty in getting renown which I think is a valid concern.
When someone from a small guild raises the issue, the answer is always some variation of "you should be able to do better". If activity is a prerequisite for advancing we should really go back to the old system - that was an activity based system that was fair with the exception of one minor glitch in their decay formula that is easily correctible. However, if we want to go to a progress-based system (reduced decay so players don't lose as much renown they earned) where it is easier to advance, we need to include small guilds like his in the party.
One obvious question I have is where is Turbine in all this? It seems extremely odd that they asked for one week of comments and never actually told us whether this system is permanent and/or what the plan is for the guilds of 10 or less that were completely left out and the guilds of 11-40 that got some benefit but should get more.
If you didn't really care about our comments/concerns Turbine, why did you ask? Why can't you give us an update on this issue since around 100 people form tiny/small guilds took the time to comment and there were many common concerns.
