Yes!
It's not 2005 anymore, and a "Flashpoint Finder" tool would be nice.
Saying that it ruins communities is ridiculous, of course. People who won't talk to each other when an LFD tool is released won't talk to each other now, so nothing is lost.
In any case, here's the deal: Bioware is going to release a version of WoW's LFD tool at some point (because people want it and it's useful); you know it, and I know it, and all of the crying in the world isn't going to stop it. So let's just put it out now and be done with it. People won't leave over the addition of the LFD tool (no, you won't), but people might leave over the absence of it. And when I say "leave," I don't mean that they'll quit in a fit of anger; I mean that they'll simply just return to the games that are more polished and complete. To all of you people who are saying "good riddance": I'm sorry, but you need those people; your own subscription is not enough to keep the game in business.
There is no patience out there to allow a new game time to develop. There is no patience, because there is no NEED for patience; there is already a game out there that has all of these tools that are now perceived to be "basic." WoW is like your spouse of 25 years: you're not blown away by them anymore, but you are comfortable with them. You may have an affair once in a while, but how many people actually make it 25 years with their spouse, and then dump them for someone new? Not many. Everybody gets one month of free play time, so Bioware has exactly one month to convince people to give up the game that they know, the characters that they have had for years, the friends that they have made, etc. and persuade them to move to SWTOR.
And yes, so sorry, a Looking For Flashpoint tool is a requirement for that.
So are UI-customizing mods, but that's a subject for a different thread.
