My rules to make running heroic and raid PUGS (Pick up Groups) easier, puns intended.
These have been boiled, sliced, and diced over my 15 years of playing MMO's starting with Everquest back in the day
Every rule has exceptions, these included.
Feel free to suggest changes or new rulz.
I will update the initial list as time allows.
Wyyll/Pemberly. (pick the game, the names are the same)
Rule 1: It's a PUG, set your expectations low.
No one is as good as you think they should be.
Rule 2: Know your role.
Tanks tank, healers heal, and dps kill stuff.
Don't do someones job for them, even if you can.
Rule 3: Need if you need, greed if you want.
Pass if you don't know the difference.
Corillary: Don't be a loot hog!
Rule 4: Don't apologize unless someone dies.
It's a game, and no one is perfect.
Rule 5: If your groupmates are idiots, leave.
Ignorant peeps and idiots are two different things.
Don't bother to tell idiots what to do, they won't change.
Ignorant people will learn, if you're nice about it.
Rule 6: Don't be a jerk.
Rule 7: Do not criticize, even if you're right.
You don't like it when others tell you what to do, and others feel the same way.
Offer suggestions and then let it go.
Rule 8: Ask questions.
If you don't know what to do, ask politely.
Peeps generally like helping others.
Rule 9: Be a follower, unless you're the tank, then lead.
There can be only one leader, and its easiest if it is the tank.
If you don't want to lead, don't be a tank.
Rule 10: Tanks pull, don't help them unless they specifically ask.
Pull agro is significant, don't mess it up or the healer usually dies.
Rule 11: If your not the tank, dump threat/agro often.
If you don't know how, learn.
Don't make the healer heal you. You're not the tank.
If the tank stinks, do less dps.
If you're the healer and the tank stinks, you're gonna die alot. Accept it.
Rule 12: Follow the kill order.
If there is't one, ask for one.
Rule 13: Load addon Deadly Boss Mobs (or better) and use it.
Rule 14: Don't run!
If your not the tank, and you get agro, run TO the tank, and not away.
Don't make the tank chase you down.
This is hard, as it contradicts basic fight or flight instincts.
Rule 15: If you're the healer, load the addon Healbot (or something better), and use it.
Rule 16: Heal the tank first, healer second, and dps if there is time.
Don't feel guilty if dps die. It happens.
Rule 17: Don't brag about dps meter (eg. recount) results. No one cares but you.
Rule 18: Learn the boss fights.
Each boss fight has "mechanics" that must be met, or it's a wipe.
Learn what your role must do so the team is sucessful.
Then be sure you do it.
Rule 19: If you wipe, try again.
2nd chances are often successful. 3rd tries not so much.
Rule 20: Gear up.
Max your gear, especially if your the tank.
People will judge you by your gear score.
Accept it, you aren't going to change them.
