I'm currently 150 Hit Rating (5.72%) and 115 Spell Penetration.

I attained that hit just with gems (+16 hit), Deadly ring of ascendacy (+38 hit) and the legs from WG (+64 hit).
It makes 8.72% hit with EP (talent).

So, I believe it's better to move to relentless dominance when upgrading (relentless ring to replace deadly included - minus 1.45% hit), or you have another opinion?
