What makes a great tank?

[Domira]

What makes a great tank is their personality type. A player who has a hostile and aggressive personality won't make a good tank. Tanks by nature are the team leaders, a leader requires a even tone personality and the ability to consider their team mates. Considering a team mate could be something like asking if you are ready for a pull or them slowing down pulls when they see the group is having trouble.

A great tank is conscious of their surroundings, this includes every thing outside of their field of vision. Great tanks are usually very good at micro managing agro, paying attention to the parties health and mana, mob positioning, mob pathing rotations etc.

Every run can't be perfect, just like dps and healers, tanks can make mistakes. Remember that.

What makes a good tank in my opinion is first of all, damage mitigation. That's pretty self-explanatory. Second is, managing HATE/ENMITY. Third is awareness of battle and usage of appropriate Defensive Cooldowns in certain events. Lastly, positioning, it's essential where you place your enemy as it is needed to prevent unnecessary walks or runs to catch up certain raid/dungeon mechanics.

Ready Check at the beginning and Ready Check before the final boss. Tank holds enmity and sets an efficient pace.

as a side opinion- I think dps should be responsible for marking/picking targets, they are the ones doing the damage so it stands to reason they should pick what they're doing damage to.
