If guardian #1 is still alive when #2 can spawn, go get #2 anyway.
I did this during last tier with a mix of normal and heroic ToT gear, and I got it the first try in p2. Did it as BM with a core hound for blood lust. You should also use those brawlers pots, and get a buff group going if you still have problems. Also flask and food.
Tbh, this fight (well, all brawler fights) are about good execution and not high gear level. That's not to say that high gear level don't make it easy. Get full normal SoO 2/2 gear, and you can burst down P2 in 15 seconds.
