There are already viable hybrid builds, just not min/max hybrid builds that you will see in trials. Go look at some of Alcast's hybrid builds...pretty impressive. But to answer the OP's question, I would prefer base damage over crit...in other words, leave it as it is. What would make hybrid builds better is to change armor passives from 5-piece to 3-piece to get the full effect. I would be very interested in seeing a DROP set like pelinial's that does the same thing with crit values though.
