MOLOTOV THROWS:

Edit this file, and change the values shown below, so that the bots do not throw the molotovs so close. If you are still not satisfied, increase the values further:

D:\SteamLibrary\steamapps\common\Left 4 Dead 2\left4dead2\ems\left4bots\cfg\const.nut

// Min survivor bot's distance to a tank for throwing molotovs

const TANK_MOLOTOV_MIN = 200;

// Minimum distance between the tank and the other survivors before throwing a molotov to a tank

const MOLOTOV_SURVIVORS_MINDISTANCE = 250;


TANK EVASION

The only effective way I've found to block the default force-to-rescue behavior of bots is this plugin from sourcemod. Be careful, since in certain situations it can be counterproductive, but so far, and properly configured, it has given me more help than problems. And remember, this still doesn't work 100%, but much better.
