To be fair strictly lore wise like roles and everything the Hunter would have scouted out the end found a way in and out talked to the vanguard or eris to start a raid, and talked to a warlock who expertise is in the hive or just has knowledge to figure out who it is and how to kill it, and finally the rule of 3 means a titan has to come, and the Hunter/warlock team would figure everything out while the titan assumed most experienced guardian would go in for the kill. So it makes sense - sincerely a Hunter
