My scenario, that happened earlier today:
- I'm playing a pug game, not the leader.
- We're in a graveyard pretty deep in.
- Wife tells me we have to go make it to a thing.
- The rest of the party sees the elevator is compound, wants to wait.
- I want to go back to haven and get my heat, but cannot wait.
- I go solo, step on the elevator. This let's me get up without inconveniencing the rest of the party.
- But I lost all my heat going solo.
Can someone explain the problem being solved by dropping all of my heat?
Because players have abused the "go solo" option in the past.
The frequency of occurrence for your situation is substantially lower than the abuse that could be conducted.
In the past, sharing health could be used to transfer heat between players. If you could go solo and keep heat, one could indefinitely heat items by simply looping the revival heat source. [Technically not indefinitely, but you probably get the picture.]
