Not only Level....I found it was AAs that made the biggest difference. I went with the Battle Cleric line EoF....and STA/INT in Kos. Took quite a few AAs before things really came together.
Once you have got your Battle Cleric line final (if you go that way), 100% Melee crits, ~15% casting speed increase, Some spell Crits as you push to the Divine Recovery cast speed/recovery boost.....mobs start droppign fast. Your DPS skyrockets as well, especially if you get yourself a slow speed/high dammage spread wep to enhance your crits.
For a test, last week I specc'd out of casting speed/Divine recovery.....and went with the 32% double attack on top of the 100% Melee crits, couple with Yaulp (another ~20% double attack and other offensive bonuses) and Fanatacism running...it was insane. Heals definitely suffered though and I miss the DR for tough moments.
Very effective for soloing though.
