I recently played on a private server to see which class i would enjoy most for wrath, and after getting very close to preraid BiS largely through the dungeon finder, i thought i could give a recent perspective on the pro’s/con’s of LFG.
For leveling group finder is AMAZING. Being able to que while questing is great, it leads to being able to do way more dungeons than you otherwise would be able to. On top of that the end of dungeon xp bonus + the reduction in travel time making levelling faster, which i feel is sorely needed for wotlk classic. With WoW classic not being a growing game like TBC was it’s very hard to find levelling groups outside of the biggest servers, so i really feel even if they remove LFG for level 80’s they should put it in until level 70 at least.
At max level group finder is so covenant, but at the end of the gearing process, i can definitely see the downsides. Throughout this entire process i haven’t made a single friend from LFG, and basically all the people on the LFG come from my server on this private server. When gearing in classic vanilla i made a lot of friends, and joined my guild. When doing the same in TBC classic, and on a private server before TBC i added a lot of people to help make groups to farm heroics etc. If i met a good tank/healer (or even dps), there was a strong incentive to add them.
For me personally i think LFG is probably a net negative for my game experience as friends/guildies are what make me enjoy this game. That being said i feel like i’m probably not in the majority in this regard. I’m fairly social, and happy to make groups, and ask people to add me. I also play on a medium population server where i know 80% of the guilds on my server, and have friends across a lot of them. I feel like there is a solid sense of community on my server even if it dimished in TBC.
i think if fall into any of the below categories, you may not make friends either way, so removing LFG will probably just be bad for you:
Playing on a dead/low pop server - have to make friends i assume, but LFG would be a god send to these servers.
Playing exclusively with guild/close group of friends. Especially in elite guild.
Not a very social player, don’t want to add people/make groups
playing on a mega server.
I feel like the above 4 groups of players may well cover at least half the player base, so i feel like there will be strong trade off’s whatever blizzard decide. I do feel like the exception is levelling though, where it’s just clearly such an improvement.
