It may have been that way originally, Fatmanrocks, but GBs have changed in their nature as well. Even with a very good blitz-level, let's say level 60 crew and a BB1 you won't have much to do in a GB.

Just let the BB1 drivers graduate, BB1's got a very short "glory time" for when you graduate blitz you are in a lot of trouble when you transfer to GB's. Imagine a BB1 (not premium) playing on a GB? I have tried that for a few levels and I tell you it isnt that easy. Lucky for me I had a sevast to help out in the early stage of grinding away from BB1.

But for people that do not have PBB's to help them grind up and leave the BB1 on GB's then its going to be a pain. I say let them graduate blitz, for after they do they wont be doing one shots for a long time in GB's.

Heck, I would rather bring a DD to a GB than bring a BB1 that does nothing at all.

Leveling a BB1 with farmer crew in GB is no harder than leveling a BB2 with non-BVE crew.

To get 900 SD in an at-level BB1 or BC you would need to have a full complete EBVE 500 expert 300 vet crew which in a BB1 it's about 9 sailors including T slot gunners R slot gunners and supports so that's about 720 olives which is equal to $37.50 but you can't buy 720 olives you would need to get 800 which is $40 just for the crew itself the boosts and those experts will run up to 450 for the boosts 600 for the vets 920 for the experts
So, to sum it up 720 for the full elite crew, 450 for boosts, 600 for vets, 920 for experts
720+450+600+920=2,690=$135 for a full EBVE BB1/BC crew
How many people truly spend that much without buying premium to get out of blitz even quicker? And also they probably wouldn't even have 900 SD at that level either maybe at most 500 SD.
