Bot mana regen rule description/default value is wrong
 

I noticed that the bot mana regen rule description is set to 3 with a description that the higher the value, the lower the mana regen. I just testing this with a lvl 50. The client regens at either 20 or 30 mana/tick while at value 3 in the bot rule the bot regens faster then that. At about 8 or so the mana regen for the bots start to rise well into the hundreds/per tick. At rule value 1 however it regens the same as clients. I also tested this with a lvl 20 client who regens at 10 mana/tick and the bots also regen at 10 mana/tick with the rule value set to 1.

From the code:

Heres the DB rules description that should be changed: "Adjust mana regen for bots, 1 is fast and higher numbers slow it down 3 is about the same as players."

The value was updated in 1746_optional_sql_bot_manaregen.sql. The description should probably be updated, but the code above is correct. 1= same as client, lower number is less, higher number is more regen as you have found.
