However, stat rolling in multiplayer would be a fucking nightmare for everyone.
All problems you mentioned are solvable. And its not even hard.
First of all, when you play with some people, you (and now i mean whole group) should be able to agree on certain rules for that game ... if you all agree on not rolling stats, then dont roll stats > problem solved. Yes, anyone can roll stats and just not tell you ... i presume you will notice tho.
Tell me honestly, do you really wish to keep a person who dont give a shit about anything and do whatever he wants?
Rag, respectfully, How much multiplayer have you played?
