CAIW should have been the first Coliseum fight
Kabam messed up by putting him 4th in the fight order.
His node is the only one where its impossible to actually hit 99 Furies. Not only does it require you to build to a total of 990 hits in less than five minutes, but the Fury passives can be prevented by glancing. As a result, even the best runs are only clearing around 50 bars.
If he'd been the first fight, clearing 50 bars in a single run would have felt great! Most normal coliseum runs only do like 6-8 bars! 50 bars? I can only dream!
But instead, his fight comes after we've already felt the joys of Knull vs Jack, Onslaught vs Squirrel Girl and Kushala vs Vox, where getting to 99 Furies is easy and clearing 150 bars in a run is common. 50 bars feels like a slog by comparison.
