First of all i wanted to say thanks for good designed web page. It has been hard for me to choose right realm from wotlk - Icecrowns is way too fast leveling and its overpopulated, at the same time Lordaeron seems perfect place to start. Problem is with RDF - most of Lordaeron population i has had honor to speak agreed that RDF is neccesery, and population would increase if it would be enabled. Reasons are as fallows:
1) Hard to get group on dungeons cause global chat is way too bissy with icc stuff (usually it takes more hours),
2) Leveling is time consumeing but we are good with that cause its 1x realm but sometimes even if u get party u have to leave your leveling and get to dungeon location, thats from my perspective is quite a waiste of time,
3)Many quests requires dungeons so, just spam for hours in global chat is not a good practise..

Its truly only a suggestion, but you guys would make our time in lordaeron more enjoyable with RDF and community bigger.
All the best wishes,
