When i started EvE i loved PvE till the point i get my Paladin t2 Battleship and every mission or combat sait/anomaly become so easy that was pointless to search for harder and more harder content 
becose there is no sutch thing …i dont wanna mention a need of bigger ship to overcome the challange , or need a given fleet whit designated rolles …
the more expensive fit is , the more hard npc fleet to face …where you see the point that you need a support ship/ logistic / tackle / Ewar and ECCM counter ships to complete the sait .
the more skill point you have for given ship when enter a combat anomaly , to become more harder and to make you find players where they are skilled to fly logi/support etc.
I wish the need of fleet in PvP to be the same as PvE , if you wanna good modules / lets players to work for it and for it price
