Not by itself, no. But when I'd also have to say:
• Also: Fast Blade, Riot Blade, in that order. You don't have them, get them on your bars. You need to make use of them. gotta keep that MP up.
• MP full or nearly full? Then Fast Blade, Savage Blade, Rage of Halorne, in that order. Use it on whatever monster is taking the most damage ie. it's going to be the one that's about to be pulled off you.
• And get.Provoke.on.your bars. You DON'T want to know what the healer is saying in my FC chat whenever he's getting smacked around because of this.
• Main menu > HUD Layout. Select "Enemy list" then move that to where you can easily see it without it being in the way. That's going to be one of your best friends when tanking. Need to monitor it to see who's doing what to whom, so you can act accordingly.
• Also, while you're in the HUD layout menu, look for "Party list" and move that to where you can easily find it without it being in the way, another very good friend of yours. You're specifically looking for the little bars underneath each class icon. Those show how much threat they got on what you have targeted. Pay close attention to them.
• Sense a theme? Don't just fight one monster until dead, switch targets often. We don't always attack what you attack.
• Always try to keep monsters in front of you, barring AoE attacks. Always try to keep still as well, so we can do our jobs properly. This is FF XIV, not The Benny Hill Show lol.
• Looking at your gear.... MY EYES! You need to choose gear with VIT on it and avoid gear that can be used by "All classes". You want gear that says something like "GLD PLD MRD WAR DRK" on it, which are specifically for tanks. Some may also have "LNC DRG" as well. Those are subpar but better than the "All classes" gear.
....then that takes up way too much time, and I'm sure the other guys didn't queue up for this (and I know that mentor sure didn't!). Not very fair to them.
