Max is cooking in the alpha channel of AIRL.
>endless leveling and Disgaea number scaling replaced with Lv.1-20, each level getting a lot harder than the last to reach, to the point where reaching Lv.20 is like reaching Lv.100 in the old version
>NPCs aren't given levels, they instead have Tier power levels, from 1 to 7. Player starts at Tier 2 when they're Lv.1, as they level up they gradually step up tiers until Lv.20 is Tier 7.
>100 HP always for everything, with checks that get bonuses/penalties depending on if an enemy is a 'higher Tier' or 'lower Tier' than you, so encounters aren't trivialized by Disgaea numbers, but you can still curbstomp low tier enemies to feel strong if you want to
I like it a lot from what I've played so far. But, it's still very buggy, as expected of something in Alpha stages (I get exp when I shouldn't, it tries to add/remove characters when it shouldn't, the economy is whack without enemy auto-drop item turned on, etc.). Looking forward to it being finished and pushed to main though, I can see myself having a 100 hour adventure in the new system and it not getting boring.
