I know practically nothing about which clan/Guild/faction is the biggest and best, but I can tell you my two cents about a lone super ship vs a decent fleet.
ok, so assuming we are not talking pvp Borg cubes here, a frigate (mass if about 3k) and a mega-battleship (gonna guess about 20k mass) then the battle cannot be decided. I the frigate is well built (high thrust, good guns etc.) and the pilot is an ace, then the mega-battleship will have to match the frigate in some way or another. Without dissecting the battle, and assuming a decent built ship for each of them, then the larger ship logically wins. But, change a variable out of the mega-battleship\'s favor (poor thrust to mass for example) then the frigate\'s chances of winning are increased. But then we must define winning. Does the pilot win by destroying the other ships core? Or making him/her flee with major battle damage? Anywho, onto fleet vs titan.
Assuming all players and AI\'s are competent enough to know how to pilot a ship and that they were all optimally built, then it comes down to tactics. Right now, any ship benefits from having good thrust to mass. The Titan can just backpedal its way to victory, but assuming they ran into some random complication (they can\'t design a ship lol) the. Then we level the ground a bit. The fleet (assuming three or more players) could win by having a large ship go toe to toe with the Titan whilst the others spelunk the turrets and shoot from the side and rear. Assuming the turrets are destroyed, then you have to wear down the shields. For my frigate (will evanty post on forums after combat trials) I have several powerful guns and 6 missle and gun turrets (and they don\'t cause eye hurt to the design!) to put as many bullets in the side of my enemies before they evaporate it with their death rays. 3:1 thrust ratio guarantees I can run like hell If I can\'t win. If all of the fleet ships are at least capable of this, then the lone Titan is screwed. It can\'t multi task once the turrets are shot off allowing the fleet ships to beat the snot out of it while the Titan pilot tries to pull a Leeroy Jenkins to save the ship. Lol I need to sleep, I will try to show you guys an explanation in the morning. If I remember lol, Good night.
Tl;dr I need to start sleeping more than over complicating things with hypotheticals. Good design and a good pilot matter. Fleet>loner Titan.
