I use 1h and shield myself. Yeah you get an extra CA with 2h, but you kind of do with 1h / shield, too - your Shield Bash. I find this to be extremely useful for countering the long cast time of my reactive lifetap. 90% of the time if I use my bash and THEN cast my reactive, I don't get interrupted (although I still fizzle sometimes LOL). Ithink it has more to do with personal preference and play style than anything else. Try both ways and see what works best for you.
