Druid speed pit farm build? Please advise :)

Fastest Druid farmer - around pit 69

Hey all!

Time poor Dad here, been rocking pulverise since season start and it slaps. Can do pit 69 in around 2 mins if it’s a good layout and dense pit. Looking for a build though that will do 90 second runs or less around pit 69.

Boulder? Shred? Fleshrender? Storm claw?

Thought I’d ask the experts before I start spending time investigating the builds above and use up all the little amount of time I do have.

Thanks.
