So will next league suck compared to Incursion loot dump league ?

I don't see how a bunch of trash and 1 chaos is a loot shower. Breach at least dropped splinters which were valuable. Abyss had cool uniques and jewels. But this is just a bunch of garbo, I can probably run a white t8 map and get more drops value wise.

As long as players have set their bar of what makes loot "good" so high that nothing gets over it, loot is going to suck. Way to fix this is to play SSF. Loot still is disappointing much of the time, but you still have hope of finding improvements.

No it isn't, its absolutely identical in SSF you pickup quality bases looking for an upgrade, in trade league you pickup quality bases looking for an upgrade or a sale it really isn't any different only its destination is different.

Players don't set the bar for whats good the developer does that with the affix rarity combined with their relative drop rates, extremely unlikely to get good rolls + high drop rate = our current shitstorm of garbage.

This is highlighted every league like breach or talisman where you have access to literally thousands of rings over the league but you probably won't find any that are actually valuable or memorable.

league mechanic is a moot point when you gate your entire endgame system(maps) around massive layers of RNG. until they fix that all leagues end in bitter disappointment
