i personally found p2 harder than p4.
in p2 i had good mods and 3/5 at relic 3 (shaak and c3p0 were g12+) but i found the opening to be super important. have to kill b2 then b1 quickly. and take full advantage of killing droidekas fast if you counter kill a magnaguard while going for b1 after killing b2. edit: took under an hour total but never felt within my control so much as it felt rng. p4 felt in my control
p4 sucked until i had a moment to swap mods. before that my b2 was for potency mostly with low speed, b1 was modded correctly, magna was modded for tankyness, droideka and assaj weren’t right. so i swapped out my malak mods to B2 for tankyness and some speed, DR mods to assaj for speed and power and then BSF mods to droideka for speed and power.. after that it took about 3-5 attempts very quickly and it was over. won with 3 or 4 alive. mods were everything. also all were r3 except b1 was r4 and magna was g12
