Who said anything about a tutorial? The suggestions in here were specifically to change the job\class trials to actually be role specific. I agree that the CNJ trials were ridiculous. In no capacity does CNJ\WHM ever DPS except as filler in groups, and in no way should that trial have ever been so DPS-centric as it was. Even the good trial, where you have to save the tree was more DPS centric than anything. You HAD to bring down the adds fast because you cannot heal through the damage to the tree. Ridiculous questline for a class that ONLY evolves into a healer.
The Gladiator trials are a *little* better, but I think the larger issue there is with tank design from the ground up. Provoke should be a low level skill, because this defines your role as a tank. Flash should be slightly more powerful than it is so it doesn't need to be spammed at the start and pray it holds. Or give gladiator a native melee AoE attack like warrior has. Something. ANYTHING. I've played both, and won't even look at my gladiator at this point because warrior is much more fluid as a tank. I have enough cross-class to mitigate and heal back damage, and as much as I loved Paladin in XI, it just isn't the same shining knight it once was. I commend all the people who took it to cap and declare it perfectly balanced - congratulations. Now go roll another character and try it again, against geared players that didn't existed when you leveled.
