Battlemaster pvp set is similar, though Valor r60 required ofc.

My Gear isn't great ( mix of centurion/champion/custom w/50 mods) and a basic concealment spec. Only the first wave is hard. I started with kaliyo out, hit Heroic Moment/relic/adrenal just as the mobs drop, get Kaliyo straight onto the elite so i don't get hit by that knock-back, drop OS/Legacy OS/legacy Lightning storm and the legacy unity cd (which i did have to buy purely for this ) make sure to interrupt that channeled cast the elite uses. Saved shield/evasion for when i was about 50% and also had a squad med unit to use. I still had to cc/kite the elite around for a little thanks to missing an interrupt. once that pack was down i switched to Lokin and just made sure one strong was cc'd, only 2 will be up at a time i think, focused the weak mobs down till they stop coming, then started on the strongs. The last guy is easy, can just los/kite him around the center if it starts getting a bit dicey, does take a while though. So what i lacked in gear Biochem probably made up for.

The H4 Black Hole quest can be solo'd as op, though can be tricky and all the time you save skipping trash you waste on the last champ boss.Think il only bother doing it once a week. edit: and thanks for this post btw
