you in a corp? if not you should be, and if you are you should leave it they aren’t a good one if they haven’t explained the basics of the activities you’re participating in.
grouping the mining lasers would not be easier or make you more isk. It would mean you need to switch rocks more often and make it harder for you to mine each rock efficiently and avoid wasting time over mining.
I saw you weren’t in a corp and that you’re only a few days old. Feel free to send me a mail in game and I can help you with the basics and hopefully find you good corp that will suit you.
