I stopped playing Scourge after about 6 weeks, returned just over a week ago as many of my guild members who stopped playing were happy to give me their stuff, with 100ex+ to spend and a headhunter belt, I made myself an insanely expensive build, a chaos damage, replica alberon strength stacking shrapnel ballista heiro, with 15 totems each doing 300k damage per projectile, firing 4 projectiles that can chain twice off a hydrosphere, against a boss it's doing around 25 million DPS, while still having 40k+ armour and 6k life and ailment immunity.
So I set about getting all 36 challenges for the first time in roughly 2 years, I have now done all content except the aspirational things like uber legion/breach/blight/delirium. I've actually really enjoyed it and it's making me feel super hyped for the next league as I want to really push for that aspiration content now.
