First off, thanks to all for the responses! I love getting home from work and finding multiple posts.
From some of the posts, I think there is some confusion maybe? The style default is to allow the Fighter to use his Intelligence modifier for attack rolls, not damage.
Now, maybe those posts were addressing the optional house-ruled bonus action? We added bonus action or reaction abilities to all the fighting styles, so I included it for that reason. But my focus is on the main description of the Fighting Style.
I added something to the fighter in both 4e and 5e that allows any mental attribute to be used as your initiative stat (call it battle ready).
I would like tactical maneuvers for the Battlemaster as the next step similar to how the Battlemaster has Charisma mods
We already house-rule Initiative can be a Dex, Int, or Wis check (player's choice).
I think I would rather do something like:
If you spend a round studying an opponent, you can add your int modifier (in addition to your str/dex modifier) to your damage rolls for your next 2 attacks against that target.
That sounds more like a feat than a Fighting Style, but the idea has merit as feat maybe.
My goal, obviously, is to increase the potential value of Intelligence to Fighters, Paladins, and Rangers. By extension, other classes might add a bit to favor a dip into those classes for a couple levels, which I am fine with.
Actually, in reviewing the Fighting Styles, maybe a feat would be better.
Tactician
Once during your turn, when you take the Attack action, you can add your Intelligence modifier to your attack roll and damage when you attack with a weapon or make an unarmed strike.
I'll update the OP with this idea. Thoughts on the feat?
