2nd macro is just Totems, then "endless" Lava Bolt.
As for the first macro, I've tried with 4 LBs between shocks, but it messes up the timing on things and my dps seems to suffer, so it's a tradeoff for being lazy I guess. I just mash one button. I can micromanage things while playing solo and using no macros and my dps goes up by about 1k. But when boxing, that's not viable.
