Heists - Solo is impossible

Solo heists are difficult, if not impossible.
The moment the alarms are triggered, there is no chance of escape.
With an army of minions if you kill wave after wave of enemies, there are more coming with skills that deplate or deny mana regen, which forces you to retreat, at which point there is no escape because to get to the escape point you have to break through... it's a vicious cycle that you have to be leve 120 to defeat these heists... what is worse with the character heists is that if you find the heists you cannot off load them in your stash, and so you are stuck carrying 5 - 6 heist items or contracts and they take up space in your inventory!

These events - heits, temple runs, or anything else besides the single game are impossible if there are no other players to tackle them, and there are no players or events taking place!

What can a player that wants to play solo do once you complete the story?
Can we reset the story and play it again? NOPE!
Can we find other players in public events? NOPE!

What can we do?? Play impossible missions, or try maps with little or no guides or tasks to complete.... wondering aimlessly through a world so massive (which is nice) but without a purpose!

I'm not sure we play the same game. I do every single l83 heist map within a minute or two and never get into any problems. And yes, I always play solo. Sorry, but I guess your build is somewhat weak.

Edit: And don't loot the green contracts from the stashes they are bs. It's completely horrible that you can not destroy them.
