Please stop simplifying and homogenizing the game. Please.

Highly disagree. The purpose of the cone is to let the WAR know to reposition themselves to hit all the enemies for the party members. By and large, if the enemies are spread farther apart where you can't hit them in a conal range, then it means one of your party members will not be able to hit the target if their AoE isn't large enough. Circle AOE range doesn't allow Line-based AoE to reach all enemies as easily if they're spread too far apart, and skills that target in a circle AoE from a mob may not reach other mobs if the targeted mob's hitbox is too big. A WAR that slightly moves mobs together after that will make it easier for all the other jobs to hit the enemies. I've usually seen other tanks fail in this regard because they don't have WAR's Conal AoE to subtly indicate they need to quickly reposition for that reason as they are only focused on their own DPS rather than making it easier for the party to DPS in addition to their own.

As for aggro management, it's a non-issue for all tanks. If you're really worried about maintaining aggro as a WAR, target at least one enemy to pull aggro towards you (assuming this enemy is linked to all other mobs), then use equilibrium to generate aggro on all mobs via healing. Due to tanks having 10x aggro generation from tank stance, it's still a non-issue.

Good lord man, have u never learned to stack mobs properly? Warrior main right here and the cone is a PITA. It also needs a target, another big PITA. Adds move while u constantly reposition for ur PITA cone. Have i mentioned that it is PITA? When SAM got its basic cone aoe replaced by a circle aoe, OMG that was like night and day. Im looking forward to this unexpected change.

I do largely agree with OP though. Kaiten removal is dumb, ninja change i feel less strongly about because i only have a rogue, but i will miss the 1 min buffs to play around with for sure. Dungeons should not be excessively difficult it is the most basic form of content that should be accessible to all and make no mistake, those less capable still struggle, it is what it is, but at least we can carry them w/o too much trouble.
