This is a game. Part of playing it is making decisions and adopting strategies which improve your odds of success. Whether that's taking out the enemy healer first, or researching what kind of food and wine the foreign envoy likes best, so you can make him really happy at the welcome feast before asking his help, or checking behind the curtains and under the rugs when you're searching a room to find a hidden door or compartment.
That kind of decisionmaking is much more compelling, engaging, and fun for me than the part of the game where I take a feat to increase my character's skill bonus so I roll higher on a check.
