Hope you don't mind me breaking down your post, but there are a lot of misconceptions about content finder and WOW's dungeon finder that I have to dispel. Omitting things that I agree with.
Not as often as you think. The kick and leave penalties for the WOW dungeon finder makes people want to cooperate, or be unable to use the tool for 40+ minutes.
Anecdotal, but this was not my experience. People were more willing to group with same-server people, and I saw more LFG shouts in WOW after dungeon finder than before. The minor stat boosts that you received as a same-server group made people want to stick with their community.-breaks down server community
-breaks down common courtesy
This is not something that the content finder does, it is something that has already happened before it was implemented. All of WOW's specs had a pre-defined role that they could not break out of. FFXIV's classes are the same. GLA and MRD are tanks, LNC, ARC, THM are DD, etc. These roles do not have a lot of wiggle room in a party setting as is.-forces the idea of set roles and set ways to play (tank, healer, etc.)
Totally not possible anymore with WOW's current iteration of dungeon finder. You can only kick ONCE per run, and main spec get a roll for their gear before off spec. There is no such thing as ninja looting anymore.-easy for people to take advantage of others (4 people que in with you, do almost the whole dungeon, and then drop you to bring in their friend so he can get the credit. Also ninja loot, etc, etc).
You take the same chances of running into morons when you do traditional grouping. You should take into consideration WOW's character model, where you can get a character to level 80/85 and dungeon-ready within a week. That is why the community is bad, why you run into a lot of poor players, and why there are so many problems with grouping outside of a guild.I consider LFGs to kinda be like mmo welfare. If you want quality play, you really need to find your own group. Otherwise, it's just a gamble on what you will end up with. If it didn't affect the rest of the community, I wouldn't be too concerned about it, but the truth is it does. And this is coming from someone that would benefit from it.
In FFXI and FFXIV, when you add a player to your friends list or join a linkshell, those players are for all intents and purposes permanent.
In entry-level dungeons, agreed. In the hard ones and heroics, does not happen.A typical random in WoW goes like this: You cue in, and quickly try to orientate yourself on where you are and who you are playing with. If you are lucky, the tank grunts to see if everyone is ready. However, usually he just takes off and half the DPS or more follows.
In two years of using the dungeon finder, scouring the forums, and talking with friends, I have seen less than 20 incidents like this. That number is minuscule when you take into consideration the hundreds of thousands of dungeon runs that are made via the dungeon finder, and is much lower than the number of inexperienced-yet-friendly people who get booted out of traditionally assembled groups. More people get booted out of pre-made PVP and raid groups in WOW because of inexperienced, than they do out of random groups made via dungeon finder.If someone gets a chance, and is brave (because people new at things typically aren't), they might pipe up and say they are new and need help. This might get them some patience from the others, or it might get them kicked.
Again, this is absolutely no different than groups assembled by traditional methods. These things are happening now, happened in WOW before dungeon finder, and happened in FFXI. This is the nature of MMOs. It's not a problem that dungeon finder introduced or exacerbated.You must be very careful to do what your role requires. If you don't play like everyone thinks you should, you might get kicked. If your dps isn't high enough, you can't take every monster in the room as tank, or you can't heal entire health bars in one shot, you might get kicked. If they don't like your gear, you might get kicked (I'm leary of addons for these reasons as well). I have witnessed examples of all of these, usually without a single bit of warning to the kickee.
Everything else you say, I agree with. Black lists, re-use timers if you get booted, only one kick allowed per run, etc. Throwing in a content finder with no limitations or protections against douchebaggery is a very bad idea, but you can add these limitations and protections with a little work and you can make it into an amazing tool for everyone.
