or you could just move judgment to another button. i use judgment of justice for the debuff on other things beating on me to slow them down or could even use judgment of light with seal of corruption and "dot" up your targets for a small HoT depending on how fast your blowing through trash..

the macros i use are

/cast [mod:shift] seal of corruption
/cast [nomod] judgement of justice
/cast [mod:alt] judgment of light


and my spam macro is
/castsequence [combat] reset=8 Consecration, holy shield, Hammer of the Righteous, Shield of Righteousness
/use [combat] 13

the trinket in my 13 slot is a 52 def trinket and when i use it it adds 152 block with a short cooldown so i spam that as well
