This is a thread I have wanted to make for quite some time now. In a nutshell it is a list of suggestions/wishes/orders for members of your party. As I have played every role and every class at least a little I think I have every point of view covered, but feel free to add something if I missed it.

From the tank

Dear healer. Do not ask for bigger pulls. I know how much aggro I can confortably manage.

Dear DPS. Pulling the mobs is MY job. If you are pulling I'm going to assume you can deal with it without me.

Dear Summoner. Your Titan-egi isn't helping. In fact it just makes things more difficult.

From the healer

Dear party members. Let's not split up, shall we? I can only heal those who are within range. If you go to the other side of the PotD floor to check teasure chest while the tank is fighting, you will be alone and likely die.

Dear ranged DPS. You really don't have to stand right next to the boss. If you are hit by every attack it just gives me unnecessary extra work.

Dear injured party member. Don't run away. If you move out of range or break line of sight I can't save you.

From the tank and the healer

Don't call me tank, healer or any variation of my class/job name. It's very rude and if I'm offended I might just let you die.

From the DPS.

Dear tank. Before you kite half the dungeon into one room check what kind of damage we do. If there is nobody with reasonable AoE damage in the group it really isn't a good idea to do big pulls all the time. Also, kiting mobs is boring for anyone who isn't a machinist or a bard. And melee DPS classes don not like it when half a dozen mobs place their AoE markers at the same time.

From the ninja

Dear tank. If I'm casting Doton it is not something for you to avoid and drag mobs out of. I have put it there for a reason.
