One thing we have discussed is giving players more control over whether they make this decision (trading higher risk for higher return) or not. In many driving games for example you have the choice of an automatic or manual transmission. Many players choose the automatic, suspecting that they are probably not going to be as fast as a player who is awesome at managing their clutch, but it means they never have to mess with the clutch and can still win plenty of races. On the other hand, imagine that the player who plays the manual perfectly is performing at 100% and the player who performs wow gold farming the manual poorly is performing at 25%. Choosing an automatic transmission for 75% performance may be perfectly acceptable. You give up a little theoretical performance in return for having less going on. Tanking can often have a lot going on. Maybe there is a talent choice that lets DKs have a more powerful Death Strike in return for weaker passive mitigation. Some players would take that talent, and some might only take it for some encounters.
