PVP is out of control in Titans. There is no cooldown period where after being attacked you cant be attacked again. Im being attacked many times a day. Its getting close to the breaking point
The game itself makes every upgrade raise the level of people that can attack you so even if you dont PVP you still get smashed and your resources stolen regularly. Its no fun being attacked by someone you have no chance winning against either on attack or defense.
Option 1: Put a cooldown period on how many times you can be attacked per day.
Option 2: Allow players to basically turn-off PVP so they cannot attack or be attacked. There would need to be a restriction this so people cant attack a number of people and then hide, so put a 24hour lock on switching from one mode to another.
