So after switching the strategy i didn't found this so hard, like it's still hard but not crazy as before, so i guess Jax is still the hardest rift on skill term I Sub1.
This is probably the most fun rift to sub1, the only annoying part was on phase 1 when you crit so much you get into phase 2 (he start summoning clones) and you don't have spray ready.
This fast summon means reset.
