Primary cause of T5 Divebomb failures

[Lemuria]

It's so that you actually pay attention to the field and those around you; since you seem to hate the ditch method. None of the other divebombs in the coils have AoE markers either.

Except, no one bothers to do that. Instead we're using an exploit where you hide in a ditch so that you can FORCE divebombs to come from a specific direction. You can't even "pay attention" to everything around you, because the camera is terrible for it. If you took the time to focus on Twintania, you'd lose the focus on the rest of the enemies you need to fight.

Yet, it is also one of the most effective mechanics in the game. Instead of running around like headless chickens, you actually have to watch where you're going.

Define 'effective'. Effective at killing players? So are dozens of other attacks. You can't watch where you're going if you don't actually know where you've been. It's not like it gives you any visual indication that you've been there, so a lot of it is guesswork. I can scarcely even figure out how anyone worked out the mechanics of it to begin with.

Because having everything handed to you is kind of boring. It's fun to figure out mechanics as a team.

Except, only a handful of people actually worked this out, the rest of us just follow guides and do as we're told. I'll say it again, the ditch method is an exploit and is almost certainly not the way to beat the fight as intended by the developers.

The fact that no one has a workable alternative shows it's a poorly designed mechanic.
