Would be real nice if you could get at least some of the loot a group gets when you join mid-map.
Say you get 100% of the tokens/heat/crowns that had been picked up before you entered the map, but only if you stay till the end. Its really annoying spending 10 energy just to show up for the last room, and it happens quite a lot.
uh no... then more people will randomly join hoping for easy tokens. This is even easier in a guild. I could imagine people actually chain doing something like this. I know exactly where my guildmates and friends are on any given level (maybe not exact location but roughly). Wouldn't be too hard to say hey man how far are you? Almost done? Let me pop in, I'll give you half of the profits.
And I have another idea about how this could be done better but I'll stop there.
What is more annoying is joining an existing party and the leader is AFK. Support this:

Because even if your method was implemented, you could still run into the problem mentioned there and be unable to profit off of that since you couldn't reach the elevator due to your useless party leader.
i think they need to fix the join mechanic rather than do something like that, no?
