if you dont understand what he did with this crew ill tell you

you need

2 elite reps as gunners - power-level until 105 ? or somewhere there, then class as reload gunners and level to 120
1 elite rep as scout - powerlevel until 120 then class
8 engys - all 10/10/12, level as support sailor until 120 then class

the crew is really lite as he has powerleveled everything and avoided the crew growth, that allows him to fit all that armor. He makes up for having no reps and powerleveled engys by having 40% vets on the crew. I havnt worked out the true ability but im assuming hes reached the repair cap with no reps at all, which is just awesome :)

to level such a crew, you would need 2 really awesome engineers on your lion2 or 1 insane engy for if you use the lion1, the rest of the crew will provide the repair and soft defence. You would have to be scoutless if you havnt leveled the scout to 120 yet. As for having 3-4 QV BO's, just for this crew .... yeah if you are leveling 4 sailors at a time ... which is the loooong way to go. If i were to do this (i have a UK bb5 crew allready which makes things easier) i would level this crew in my AA ship untill 90, then i would level the scout and the gunners on another bb crew until the gunners were usable, then i would put everything on the lion2 and level everything to 120.

If you really want to do this, you have to complete it, you wont even be able to sell it if you decide to give up because the crew will become worthless if you class early.

I think you could do this differently with similar results and a lot less headache. You would end up with a lot more versatile crew and have a lot more fun lvls 1-119.
BO-Same thing 14 Pot/ 12 Rep, max vets fewest sailors possible
Scout- normal but shave off a lot of rookies to reduce weight
Gunners-Elite ACC classed reload, Max vets, reduce weight until RLD cap is just barely reached
Supports-Normal classed and max vetted
4 skeleton sailors-one being an additional scout with no sailors on it

I haven't done the math but I think you would have a crew with similar weight, more OH time and near rep cap (depending on layout), and it wouldn't be such a pain in the ass to lvl

have 2 stripped normal scouts ( thats 1650 less sailors from a normal crew)

and 2 stripped gunners in T slots (thats 2000 less)

Then strip 300 rookies off each main gunner

thats about 4250 sailors right there

with 5 engy and 2 reps you will need 380 vets on them all in order to rep cap, and you will OH for just over 6 minutes. Your scouts wont be aaw immune though :P

2 strip rookies 1300 rookies, since max is 650. Unless you got a mod crew.

UK Gunners is impossible to gimp unless, you delay class your heavy gunner as hell.
But then who would delay class that far.why not just power lvling since we are at it :P?
