grimoire score is a good start point if u dont know at all the player joined your team and plz to those ppl always chatting about grimoire is only shit cuz its easy collect ghosts. remember that when u have done collecting all the 77 ghosts u only get 540 grimoire points so if a player has more than 3000 it means he played a lot and spent time doing pvp and pve things besides ghosts. anyway i like play with almost everyone and i really dot f##king care about their skills. but yes i agree when i meet a low grimoire guy i get a lill more serious and help him as i can ^+^ love destiny <3
