fun fact, actually nothing fun about it, but this wining began in CAT. The problem is not that cruisers where nerfed...they just did get the same amount of attention as everything else did, so they got left behind only to be played by players whom understand and know the game like the back of there hand. Easily compared to WoT's Maus, the Maus is not a good tank, not by a long stretch but it can be used to extremes by potent players thus deemed balanced since below average players will simply be uther crapin it. Same is the case of cruisers in WoWs right now, the average BB is NOT good! this is to no disrespect to BB players but what ships will be most likely know by people that just started the game? BBs! So despite the fact they suck they grind there way up to T IX and X and then complane that there are not kicking absolute [edited]in these (fabled) monsters. Only to go and whine about it on the forums. and to try and make everyone happy WG nerf's the things these less competent players struggle most with.
Both sides of the coin are true, BB are getting out of hand and CR are left behind in this all out arms race.
