First of all tanking takes a special breed of people to be able to consider it "fun". For me I like high hp and high defense. High attack is a bonus which is why I main a War. All I can say is that there is not enough of a difference between the two current tanks. I think SE missed an opportunity for both pld and war jobs. The pld needs to have access to to raise (in battle) and cure II. The war needs more drain skills or at least more offensive cd's to get the dps interested in running a tank.

As for low dps of tanks, well... no shit they have low dps. They're TANKS! People who say that tanks lack dps and aren't fun because of it are wasting their breath. The real gripe with why people think tanks are no fun is because of the added pressure and responsibility of keeping yourself/party safe. There is a thread on this in the Tank Section and I would say the consensus is clear.
