Just a few things I can see, I don't have a brute but my main is a scrap claws/sr
Just in general you have way to many LotG sets, remember the rule of 5. If i counted right you have 7 total sets so the last 2 are pointless.
Typically Follow Up is slotted as an attack, although it may be different for you brutes.
Dont need the 2 slots in practiced brawler, it will recharge in more than enough time, and with your amount of rech you are better off with just and End Reducer in the default slot
Probably wouldn't slot shockwave the way you did, if anything take the slot from PB and one from Shockwave and throw it in Stamina to get the AOE bonus from that and 5 slot Posi blast into shockwave for more rech
Also I am not sure how far over the softcap you are wanting to go but if needed to you could play around with the sets and maybe gain more rech/hp/regen/recovery etc and just lose a little bit of buffer
Hope this helps
was curious about my build opinions thoughts im currently lvl 20 as i just made this toon a couple days ago.
