Personal experience, ignore if you want. Back in WoW before the dungeon finder (Vanilla), it was extremely easy to find a group, and I made quite a few e-friends that way. All you had to do was use the current tools that were already implemented. It really isn't so bad to scroll down the list of a /who 50 or a /who #-# and whisper them. Even if people turn you down, you at least "talk" to them. They may say, "Oh. I have to go do something for like 35 minutes, but if you're looking for someone after that, I'll definitely be down." Bam, back-up plan. Now you're more likely to talk to them again because you'll remember they'll be on once you're down with the other fp. I will give that it IS convenient, but it is something not entirely necessary. I wouldn't not use the LFG tool if it were implemented-- that would just be stupid. But realize that it "does" stifle communication. And more often than not, a LFG made group turns into, "CC arrow" "Boss does ..." And never a, "Hey, this was a great time. Why don't you msg me later if you're looking for another DPS/Tank/Healer. My alt's name is [this]". By greeting them first in /whispers I've been more open, I've talked to them a bit more about something they're doing if they need to afk for 5 mins before an invite, etc. TL;DR Implement it if you want, but they "are" justified when talking about dungeon finder ruining a community. It really isn't that hard to /who for 5 minutes.
