after a few days experiencing the ptr, i am clear that diablo 4 has finally found its direction.
the season 6 ptr focuses on making nightmare dungeon missions more relevant. previously, players only aimed to reach the final boss for upgrading glyphs xp, ignoring side missions and monsters. (i mentioned before that saving that 3 dudes in the NMD side mission gets rewarded by 2 rare gears after waves of elite monster, dunno which joker designed it)
now, nightmare dungeon missions provide crafting materials thus encouraging exploration. players are potentially hunt down every elites there because the obducite and gems drop is very lucrative, thats the genuine feeling for a rpg venturing into the dungeons!
then we have the pit that offers glyph xp based on tier difficulty, its becoming totally relevant as players want to level up their glyphs, they just need to blast all the way down, capability directly translated into proficiency, no more nonsense.
finally, i assumed the infernal hordes mission is expected to reward players with gear drops, especially the soon becoming very rare ancestral grade.
already one year journey down the road, better late than never.
