Right now i dont know if i understand this well but im a Rogue1/fighter1/Ranger5 so a BAB+6 , beside my detail window for the Main hand weapon i have only +12 did im not suppose to have +12/+7 instead ???? I ask the DM in the game and he just give me the answer : The calculation of this is very complicated and if you have a issue send a bug report. But this did't solve my problem at all . So did i suppose to have 1 number beside my Main weapon or 2 ???? and if im supppose to have 2 that mean all my characters are stuck with only 1 attack because i have a fighter 12 and he have the same issue. Hope someone can answer me with that because im not very impressed by the DM answer he give me there.
