Nerf the god damn pets, it's very simple

. SE was brain dead when they created a mob that summoned easily killable VT pets, that's a fault of the mobs, the fact that some BLM was smart enough to exploit it isn't something that should be punished by revamping the entire job. Comparing WAR's (or any melee for that matter) to BLM is like comparing apples to oranges.
By selecting to play as a WAR you sacrifice the ability to dish out damage equivalent to your manapool in turn for being able to take hits, feasibly use utsusemi, transfer any generated hate to another person, get drops from hnm

, etcera, etcetera. If warriors were able to generate 1500 damage out of thin air, recast utsusemi until they lost hate, use a weaponskill shortly after and finish off with another 1500 damage nuke coming from a nonexistant manapool it would be time to nerf WAR.
BLMs are not overpowered, SE has just not had the foresight (something which they've lacked when making a lot of decisions) to make a select number of situations which happen to be easily exploitable by the BLM class. Nerf RDMs for their incredible soloing ability, nerf utsusemi again for being able to absorb all direct damage, nerf THF main and sub for being able to transfer hate to someone else, nerf BST for making teh petz atak eachothur, and in actual seriousness, nerf retarted mobs that make the BLM job the crucified posterboy of the FFXI world.
BRB gonna go get critical'd by nidhogg for 100000 damage.
