If bb chosen the fruits for his crew he took a big L ngl
Only augurs is overpowered hopefully Lafittes is banger that oda is Holding it back for so long
I wouldn't be too quick to jump to that conclusion.
Don't underestimate Teach's knowledge of Devil Fruits.
It's true that the Blackbeard Pirates DFs don't really stand out much especially when you compare them to the Logia or even some of the mythical zoans but Teach and his boys are clearly choosing affinity over optics.
"The Supersonic" Van Arugur -> Warp Warp Fruit
"God of Death" -> Sick Sick Fruit
"Champion" Burgess -> Strength Strength Fruit
and so on....
Just like we have affinity for Haki and affinity has a strong influence on how far you can take Haki (i.e. affinity for CoO -> FS), the same might also be true for Devil Fruits and said affinity could potentially be the difference between it taking a life time to awaken a DF or it taking just a few months.
Blackbeard Pirates are going to be very impressive when we finally get to see them in action properly.
Also if you're ever in doubt and think a DF is lame, remember Luffy.
Luffy's gomu gomu fruit became the Nika Fruit when it awakened so who knows maybe the Blackbeard Pirates DFs undergo a similar transformation.
One thing Luffy shares in common with the BB Pirates like I've pointed out above is "affinity" with his DF.
Moreover keep in mind that info about Nika wasn't in the Devil Fruit Encyclopedia so who knows maybe there are some DFs out there that are similar as well, DFs with hidden potential that we just don't know about yet ^^
