That might be way better than IAS. Do some math for you:
Assume IAS is a 10% overall increase in DPS (based on standard increments in DPS from Fastest(3) to Fastest(2)), and that you haven't reached IAS cap (see the Attack Speed Reference thread for more info).
Let average damage be x before criticals.
Assume you are not using any EQ that boosts crit damage in any way. Therefore, with Star Gazer and Mastery, you will have +45% min crit and +60% max crit damage. Therefore, crit damage range is (1.2 * 1.45) ~ (1.5 * 1.6) = 1.74 ~ 2.4. Representing as an average, averagecritdmg = 2.07.
Crit rate = y, and therefore rate of noncrits = 1 - y. Dmg = x*crit*averagecritdmg + x*noncrits = 2.07*y*x + (1 - y)*x == (1 + 1.07y)x
Before: Dmg = (1 + 1.07*0.63)x == 1.67x
After crit rate boost: Dmg = (1 + 1.07*0.91)x == 1.97x
Average damage boost: 1.97x / 1.67x = 1.18 > 1.1 for a general IAS damage increase.
Therefore: Keep this inner ability.
