World First tank line up confirmed

[Reynhart]

And how many times has SE gone back and gave reworks to tanks? I mean wasn't pld left mostly untouched during 3.0?

No, PLD was tweaked at almost each major patch.
As an example, these are the changes it received at 3.2 :

• Fast Blade

  TP cost has been reduced from 70 to 60.

• Savage Blade

  The amount of enmity generated has been increased.

• Goring Blade

  Potency when used as a combo action has been increased from 220 to 240.

  Damage over time potency has been increased from 40 to 50.

• Royal Authority

  Potency when used as a combo action has been increased from 340 to 350.

• Clemency

  Casting time reduced from 3 to 2 seconds.

• Divine Veil

  The protective barrier that is cast on all party members within range when you receive a healing spell now activates even when healing yourself.

  Recast time reduced from 150 seconds to 120 seconds.

• Sword Oath

  Use will no longer interrupt weaponskill combos.

• Shield Oath

  Use will no longer interrupt weaponskill combos.

  Damage penalty has been reduced from 20% to 15%.

  The amount of enmity generated has been increased.

That's a lot of small changes, but I the same kind of changes would help DRK be a lot better.
