If modifiers and curses are supposed to make trials difficult, then progress in the wastes should matter as well, but it doesn’t affect trial chests. You can get something stupidly difficult early on and something too easy later on. This happens in the extreme with trial chests, while no other game mechanic in the chaos wastes is so averse to scaling with progress.
But with the Bannerman and Bestigor tiral combined with Khorne Champions is vastly more difficult than any other trial is at that point in the game. I don’t have the numbers, but I know that Khorne champions buff each other and everything else. Combine that with the effect of a banner, which seems to double their health, and you got a challenge that is just stupid as you kite them around till you hit a dead-end trying to pick off banners; the longer this goes on, the more likely you’ll get split from the team and picked off by specials or stamina/dodge depletion.
With no majorly OP boons that have been removed like Tempest, Vaul’s Anvil, and Twined Arrow, and you haven’t got lucky with weapon traits, the best case scenario’s I’ve had for winning this are when the team abuses Trollhammer, Ult Cooldown boons (Hekarti’s/Xokha’s), and/or Morgrim’s Bomb with duplication; in fact, it’s almost dependent on strategizing your team around dealing with powerful groups of elites by using Trollhammer, Battle Wiz Coruscation/FlameWalk, and Stagger Tanks like FK and IB.
With the lack of decent ranged boons, if you’re playing BH or even the OP Bloodshot Waystalker, it’s not favorable late game due to the lower stamina and health pool since they can’t kill things fast enough at range like they can in the Campaign where you get to pick all your item traits and properties. Ranged classes seem to suffer more in the wastes since they depend on being able to hit breakpoints necessary to quickly dispatch threats before they get overwhelmed.
I’ve noticed the CW meta seems to have shifted in favor of specialized highly durable builds that Stagger a lot and/or can stack power bonuses. Damage isn’t a huge issue if you can eventually wear your enemies down as you constantly stagger them. To do this well, develop a durability pool with regen perks, temp health, and damage reduction; combine that with ability cooldown, and that’s generally the winning combo. Most other perks are just extra, but the ones to aim for consistently are durability or cooldown related. You might go for are power stacking boons or stiff that compliments specific talents, but you need that durability and those breakpoints for stagger. The meta is favoring stagger tanks that take out elites/specials now, rather than grudge mark killers; you only really need to worry about nasty grudge marks on the last mission and by then you either have the boons you need to deal with them, or you’re screwed anyway.
