Native is good.
cRPG is better for casuals.
The only real advantage of Native is that it provides a 100% level playing field so clans can compete against each other wherein the only variables involved in determing the victor are tactics and skill.
cRPG involves gear, stats, current build (lacking the ability to adapt to the enemy composition), then tactics then skill.
Really, both have their place and I enjoy playing both. I play cRPG casually and for fun, and I play my battle and duel tournaments in Native.
