Yeah that's exactly my conclusion as well depending how your first 2-3 job pulls went, but they do become less useful as you breach 5-ish job summons. (unless you have hilariously bad luck and pull all t2 classes that start with 3 speed)
Like, as I mentioned earlier I did both Dark Lord/Royal Guard and Combat Surgeon/Archmage pairs, so I'm good for warrior/mage setups, but I'm still tempted to deep dive the base daggers deck. Lord knows the moment I do that I'm going to pull two daggers jobs.
I guess I'll wait and see how the 5-8 panel stacks up in terms of flexibility over power, but then again by then I'd have probably maxed out all my existing job cards anyway. Seemed like a shit ton of Skillseeds requirements but we were comparing the first two weeks of the game with the first 12-16 weeks. That's almost a magnitude of difference.
