"Repeating a Raid ... for nothing?"

#PokemonGO: I am wondering if it would be a good idea to repeat a raid for nothing.... meaning, after you complete a raid, you can do the same raid again. And if you complete it again, you will get nothing. No extra XP, no gym points, no stardust, no resources, and no another chance to catch the raid boss.Why? I seems to have lost count of the number of times a raid is completed... and then later, while people are still around, friends show up. Or we complete a raid, only to find out one of the raiders error out and couldn't get back in. It would be great to help friends complete a raid. I certainly would be willing to use resources (revives and potions) to help out a friend.What do you all think? via /r/pokemongo http://bit.ly/2WIxtBD
