Back in the day before the BC nerf, the Battle cruiser was the choice of ship for PvP.
It was just amazing for multiple aspects of the game. Their nerf, the FW changes for ship limitations in complexes, and gate gun mechanics changes led to the issues thst forced me out of the game.
This is the chronilogical order of issues that came about directly from these changes.
FW discouraged the use of BC in lowsec. Before the nerf of the BC, frigs and destroyers needed to work in buddy groups to take on BC, they didnt straight outclass a BC by themselves minus the OP Dramiel at the time. (Ccp nerfed the Dramiel and then buffed all the rest of the frigs to damn near Dramiel OP levels)
For people that are looking for fights ,especially in lowsec, flying in a BC means that you won’t be able to defend FW space as a frig can flip a system in a novice over time. So you must fly T1 / pirate frigs to take on the opportunities to fight(which are limited due to a dwindling player base)
Less BC use presented less targets for BS hulls in lowsec. BS escalations were down right fun to be a part of and fun to take on. BS could actually be outclassed by solo frigs and destroyers by themselves due to sig radius and angular velocity. But this was balanced by the use of BC/ cruisers on the field. Frigs filled the roll of a quick tackeling ship rather than the primary DPS of the fight. Frig ewar was extremely useful and led to actual measurable outcomes in fights.
Less BS hull usage in lowsec presented fewer and fewer targets for carrier escalation. People would be inclined to use carriers more haphazardly when it was presented with actual targets rather than a fleet of frigs which would almost always doom a carrier.
Long story short the changes ultimately alienated anything above cruiser sized hulls for not on FW but the entire game as well due to a massive drop in target oppertunity.
