Having them ≠ Using them.
jonesskill has a point... these ridiculous suggestions to make big ships useless are usually coming from hull-/hybrid-tankers. If they really used a big ship for combat, they would know, they are already crippled to the brink of uselessness, with all those ridiculous special effect like TLB, FC, DF etc. going on. Reliable and strong shields is all they have got going for them... take that away (either directly or under the disguise of a new direct shield-booster-attack mecahnics) and that's it.
At least be honest and just demand to remove big ships entirely from the game, because you don't like them.
So you are calling invincible PVE ships "crippled to the brink of uselessness"...
I wonder how they are able to make things like that AFK farming res.
In PVP, everybody knows big ships are impossible to kill in 1v1, you simply need to fit all hardpoints with turrets and take a figher bay, set to 402 then sit there. Medium ships simply don't have enough ammo or DPS to crack your 7000mj shield and 10000mj SCBs. Not even with feedback cascade rails or synthesis.
Wing fight is probably the only thing big ships not good at, just because of the slow speed. But as long as you are able to use fixed lasers, and your wingmates are not complete idiots and know to fight near you, that can be solved.
Effects like TLB, feedback cascade and dispersal field work not only on large ships, but also other ships.
And speaking of hull/hybrid tanks, there are simply too many biases against them. Effects like scramble and corrosive, external and internal module damage, and the very low health pool...
