Need More ISK, Need More DPS

Greetings fellow human, how is your day today? I've been devoting a lot of my free time to this game called EVE Online, because it's pretty awesome and so on. My main problem right now is making enough ISK to satisfy my needs of bigger and better ships. Does anyone play the game, if so, how do you make your ingame cash? I'm trying LVL4 missions right now and it's... meh.

Picture related, this ship is bad-ass.

Also regarding WoW, why do I do the same dps (as fury) when I keep a full rotation (BT>RB>HS>Slam) as when I just do BT>HS? Weird. Bad. Who cares.

Have a good day!
