Let me tell you a small story.
I’ve purchased ( I know ) DF to give it a try because of some friends. I leveled from 60-70 in… 10 hours. I can’t even remember 1 zone, npc who I can say “Man, I remember this guy ( or zone ) from when I leveled up ).” . Yes, that’s bad it is.
I’ve also qued for RDF, 5 times I think while leveling. Well, I had literally no idea wtf was happening. No one was even talking. Tank just jumped in, pulled all the dungeon, died once, then /quit because “we can’t keep up”. Like wtf?
Great, I said, bah, is fine, let me get to 70 because maybe things will change. I did, then jumped into Normal to be “ready” for Heroic … just to be ready for Mythic , then M+ … you got the point. Only to find myself in the same spot No one was talking while entered a dungeon from RDF. Everything was “hurry , hurry hurry”. All good, except if something bad happened, like a wipe, healer or tank would 95% likely to leave and then wait for a replacement which made the whole …Random Dungeon Finder a pathetic tool because…“no one cares dude”.
You don’t see this in WoTLK. 95% of the dungeons I made, people usually communicate, takes their time if needed, etc. At the beginning of the x-pac, there were times were we wiped 2-3-4 times, with no one leaving, but just keep going and making fun of the situation. If I was on Retail, the party would of been gone after the 2nd wipe … max.
And don’t believe that if they will add RDF everything will be so good. Unless you are a Tank or Healer, your waiting times will be 15-20+ mins ( at prime time) at end game at least. In that 15+ mins I can make a party right now with the in-game Tool in WoTLK without problems.
RDF will bring nothing good to the community. If I love something about Classic is the community and how nice ( in general ) people are. You do not see this on Retail. If you want to …trade that for a bit of faster leveling ( maybe ) and some lower waitings while trying to do a dungeon … that’s fine. But I do not want that. Retail is a Mobile Game right now with nothing good to it, except maybe the combat.
So from my POV, they should not add RDF. Let us be …Classic. Make it the old way.
