i noticed higher usage of RAM too but nothing noticable irl and after optimizing, i free RAM just as much as I could with stick launcher. as for battery, I actually get better battery with GNL than stock launcher. as for whole nova vs gnl, do you like your launcher? are you productive with it? yes? great! then shut up with your whining. people use their phones in drastically different ways so they have different needs. do you think that there will be somebody who just makes phone calls and write text messages want to mess around with nova launcher? no! do you think there is someone who is customizing his/her phone and getting most of his/her phone want to use gnl? maybe for 5 minutes!
