This is such a shitty statement to make. Most of us who are complaining about 5.0 DRK played the job because they enjoyed it as it was (mostly HW's iteration) in the first place. The job's playstyle keeps getting butchered expansion after expansion since its release and it's no longer enjoyable to us, and you're telling us that we should just stop playing it and go main another job ? What the hell ? What if DRK used to be our favourite by far ? What about the people who actually don't like anything else despite having tried everything ? (I'm not one of them, I enjoy all tanks and a lot of other jobs too, but some people are like that). What about people who love the aesthetics of the job and want it to be back to its more enjoyable state so that they can keep being an edgelord while still having fun ? We love DRK, we want it to be good. We don't want stop playing it because it feels like shit and then move on to another job. We want THIS job to feel as good as it used to feel because WE were playing it since the beginning and loved it. You're reminding me of people telling other people who complain about some things in the game (like formula becoming stale etc) to stop playing the game and find another game. If we're criticizing something, it's generally because we love it and want it to be good. If we didn't like it and thus didn't care, we wouldn't be complaining in the first place.
Still looks worse than HW or SB AoE. On top of that, we aren't complaining about AoE that much since it matters a lot less than boss fights.
No it won't be challenging at all. Rotations have been mathed. You'll just blow everything at the start and spam Souleater the rest of the time without spending MP for almost a full minute. It won't ever overcap since the regen is very slow. Darkside will stay up since it lasts for 60 seconds. TBN is a non-issue since it just has to replace an EoS at some point if there's a tank buster and you get it back when it breaks. You simply wouldn't use TBN outside of tank busters because of its high risk of not breaking. It's high risk 0 reward.
It won't become challenging since you won't use it outside of it being guaranteed to break for the reasons above.
We aren't complaining that much about CDs. It's about the feel of the job. It's really not that well thought out when you compare it to what the other tanks have. It's just there to give the job a fake flavour.
