Stop helping slay bosses

So I've officially decided to no longer help players slay bosses so they can traverse the game.
It always ends up with ungrateful players swiping up the drops while you do all the work and gloat about what great drops they got.
Now I'm under no illusion that they need to share the items but coming up and swiping and gloating is just that last middle finger and I'm done with it.
I am happy to help out struggling players and often drop items from my stash for them. /rant

Sorry, but I can't quite comprehend your frustration.
Normally the rushed players
gets the drops and the rusher gets a price that was agreed on, The Hellforge, an Ist/ Mal etc. So, they don't "swipe", they pick up "their" loot. Let them be happy about their drops. If you are jealous of their drops, you should either negotiate that you can pick up loot, too, or you do as you have said, just don't rush people if you don't want to help them.
By the way, how often does it happen that players find great items in the course of a (or several) short boss rushes? Not often. If you can negotiate a Mal or Ist as your payment, it will most likely be more valuable than the drops in most cases.

I've just been hopping around helping out when I can for nothing. I jumped into a normal Baal run game. After I got to the team at the Throne, everyone left a few seconds latter. I hope they didn't get disconnected. But I was baffled why they all left. I didn't want anything and I wasn't going to pick up a thing. Just wanted to help.

If I decide to help other guys, I leave drops to them, even if it's high runes.

I like to help for free since I was helped for free in the beginning, paying it forward so to speak. Plus, I like flexing on Ubers/Ancients now, so everybody wins
