So I was always on the fence when it came to LFG Tool debates however after last night I definitely decided SWTOR needs a LFG tool. I'm on a heavy server and despite 200 online at the Imperial Fleet I couldn't get a group for any of the 20-30 Flashpoints after trying for an hour! Eventually I just gave up and logged another character, whereas a LFG tool could've put me in a server wide queue broadening my search whilst enabling me to quest too and not waste an hour spamming chat...
Now I know the big argument is IT KILLS COMMUNITY (which i personally believe is bs but that's another debate) so in order to counter this simply limit it to your server
