Issues with pro,
Can make your player insanely powerfull with the right perks in combat.
At luck 7 gambling is no gamble just a slogging match.
Boosts skills for some reason.
Anti.
Droping it below 5 is more negative than any other stat, unbalancing S.P.E.C.I.A.L selection when making a character.
The lower it is the less chance of defeating higher tier foes, especially with a non ranged or custom build.
At 5 gambling throws up some laughable patterns...
Example the dealer draws two face cards often the same suit and rank 40+ %, you draw 2 - 4 then a ten / face next card comes up ten face same amount of % as the two faces for the dealer.
You draw 5 cards you go over, the dealer does so chances are he'll get 21.
The dealer gets blackjack three times in a row, possible for you but not unless you boost luck.
So what I'm saying is the stat to my mind is only balanced due to extremes, and is there really a need for it to be so.
Would it be better just to play more of a minor role, a little tweak behind the scenes rather than influence things more than the other stats.
What are everyone elses views.
