New player who picked up Ogryn and has fallen in love with the Heavy Stubber. Any advice?

Specifically the Achlys it's really nice for hitting those pesky range Elites with the extra zoom and for doing serious damage on the big un's. Any advice on blessings and what not?

I'm still trying to find a Melee I like currently using a Shield and Club which feels OK but not great. Any Ogryn mains have a melee to recommend.

I'm also a controller player if that means anything.
