Particularly for power builds. Nothing competes well with Scholar. In fact I'm not even sure scholar would lose out to say eagle or Ogre if you didn't have 100% uptime on the damage bonus: Ogre's doesn't give a good bonus outside the 4% bonus and Eagle's lacks power - power is still way more valuable than precision in most cases. Eagle's is very situational as it's possible to overcap crit depending on the gear setup (some power builds already feature some assasin's making the precision less valuable). There's not really anything else that gives the huge bonuses that scholar does at tier 6 and always gives probably the best stats for power dps - power and ferocity.
