I feel like these raid points are missing the whole "raid" aspect. As it is now, like someone above said before, people are simply logging out with an alt and killing it once it respawns by themselves. Sure, it takes a minute because of the health but eventually they'll take it. I suggest that we add "stages" where the raid points summon ninjas from the village (not as strong as jonins, obviously weaker) to defend them and perhaps progressively get harder or more spawn. For example:
Stage 1: Raid Point reaches 75% HP. Summon two Chunins (NPC) ninjas that are rooted near the raid point (meaning they will tp back if their target gets too far) and defend it from threats.
Stage 2: Raid Point reaches 50% HP. Summons four Chunins (NPC) ninjas that are rooted near the raid point (meaning they will tp back if their target gets too far) and defend it from threats.
And so fourth, not sure what Stage 1 would bring to the table at 25% HP. These NPCs will not be as hard as the Jonin NPC but difficult enough that you'll need a TEAM to kill them off without risk of death.
What does this accomplish? This brings in the whole "RAID" aspect to the raid points rather than having a single person kill them with ease.
