Don't be "that DPS"

[nitaZ28]

What about when a tank refuses to use AoE,doesn't mark a thing, and switches targets every 2 seconds to fast blade one thing, savage blade another, rage of halone another after that and fast blade the first one again? That's ineffective vs. a DPS who is attacking whomever the tank attacked first and to DPS who frequently AoE.

DPS should not blindly assist tank. Depending on the tank class, most are gonna be switching around. Especially on PLD.

It's simply a more efficient use of your resource to be landing your chain enmity skills on extra mobs (as possible, depending on the status of aggro on central target) than it is to be using your AoE enmity generators.
Poor resource spending isn't always a visible thing, and may not matter depending on gear/levels vs. content. But when it DOES matter, it matters a LOT. It can be the difference between comfortably controlling a bad situation or extended fight, or your group getting wiped.

That's not to excuse the tank that isn't telling his DPS who the central target is (via marks is easiest), or isn't remaining aware and alert about the status of aggro on that mob.

When tanking, I prefer to make it as idiot-proof as possible for the rest of the group. Years of experience at this has taught me. Running a group, especially after the invention of the "dungeon finder" system for MMORPGs, is a lot like herding cats.

If I had a nickel for every time the mob marked with the big "1" over it's head was the LAST MAN STANDING? I'd be running for PoTUS.

You don't have to switch unless there's a problem/troublemaker most of the time. A problem such as DPS being a bit too strong for flash, in my cases that doesn't happen often, or if flash is out of range. It's also easier for DPS to know who your main target is by focusing your single target attacks on a single target.

Worrying about Resources as a PLD is one of the most short sighted things you can think about as a paladin. You have the tools to restore your MP. Where shelltron will always give you back MP equal to flash's cost, and you can take advantage of riot blade, which leads to Gore Blade. Taking advantage of your MP eliminates TP issues assuming you did not spam lob and bash excessively, in dungeons it's a huge stretch because of the downtime between groups + doors. The constant downtime in bosses is also a huge factor to why the resource problem is moot.

There are literally PLDs who still freak out about MP when at 85% today.
