A better LFG tool is one of the most urgent things this game needs right now, imo. I started leveling up as a healer, but respec'd to dps because most of the time I was solo. I always try to use the tool in the game, but it NEVER got me into a group. Not only this tool is very limited in use, but people tend to ignore it. There should be more incentive to flag yourself as LFG, maybe automatically adding people to LFG when they take a flashpoint/heroic quest. Also, searching for people who need a specific quest should be easier. Anyway, the fact that I'm ending up playing an MMO mostly solo is really disappointing. A lot of good content is going to waste.
