I play games for fun. I strive to have as much fun as I can while doing do.
I'll always make something that's effective at the skillset that I choose and I'll play to the best of my ability. Until I notice that's too easy. I'll increase the difficulty until that too is too easy. Then I'll find other things to make it more fun. But I don't use cheese, or actively make some sort of stupidly OP broken build. Steamrolling through a game is just flat out boring to me.
Lastly, in a narrative driven game, I tend to engage in combat in a narrative driven manner. So my Rogue will instigate an ambush, but my Paladin would walk straight in one and formally declare war on the evildoers.
