Hugest probem your BS face still is their weaponary
Yes, but you should still be able to fit a full compliment of them if you remove a mid to make into a hardpoint.
(while all others get more slots not less...)
Think about it from the fleet sniper perspective, to get 150km range and tank you need to have the 1400mm t2 arties. But you also need to have at least 2 sensor boosters and 2 tracking computers (or enhancers) and you really need gyros as well.
So now a mid is removed.
Which means you will only be able to fit 2 boosters and 1 tracking computer so you will need one low for the enhancer where you already use 2 slots for rcu2s when using 6 guns, with 7 even with the increase in grid you won't be able to remove either. Niether will you want to remove a plate, eanm or dc2 which leaves the single gyro to remove. That gyro adds 22% damage... Another turret adds somewhere around 17%.
So in total a complete and utter NERF to the fleet pest for sniping duties at least.
