I love how half the people have no clue what they're talking about. I'm willing to wager most of them played 4 matches and gave up cause it's "too imbalanced"

Firstly, about sleep. You have a healer on your team.. every match. Esuna/Leeches takes 1 sec to cast. It takes pure luck to get a 'damage interrupt' on that. Healers need to remember that skill exists.
secondly, melee hitboxing. My computer doesn't technically meet the minimum requirements of FFXIV and i have very little problem functioning as a WAR in pvp. Never getting the "too far away" error when im on them.
thirdly, ill follow what this thread is asking for after the above tips to save some of you from frustrations.

1) Lack of players at the moment
2) Lack of variant compositions
3) respec cost, ill certainly agree with that one
