In recency, multiple ADV players have expressed a disinterest in the current state of ADV NU. I want to raise discussion on the tier's status for increased visibility across Smogon, as most of discussion regarding ADV NU happens on Discord (which sparked the creation of this PR thread), to see the general consensus in the ADV NU playerbase on if the tier needs change and how to accomplish it. Here are some problems people have addressed about the tier so far:
One of the main issues regarding ADV NU is how Glalie warps the tier around itself. In a tier with very limited hazard removal, Glalie manages to attain one Spike minimum in every game to enable powerful breakers like Hitmonchan Flareon and Haunter with ease, and limiting Glalies opportunities to set Spikes or removing them once they've been set is a tall task considering its good Speed tier, Light Screen to gain more ups against would-be answers like Flareon and Torkoal, and Explosion to check any Spikes response. Glalie is so effective at its job that ADV NU is heavily centralized around trying to prevent Glalie from rummaging through teams while letting your own Glalie gain a Spikes advantage. This dynamic of the tier being nothing but Glalie Spikes offense is not perceived as healthy, with multiple players calling out for action to be taken regarding the snowball. If anything were to be the main focal point for taking action regarding ADV NU, it should be Glalie.
Haunter dropped into NU with the NFE unban, although technically UU by viability as demonstrated in recent ADV UU tours when UU's NFE unban was introduced far after, meaning Haunter might not have been tiered quite correctly. Haunter's power level is on par with the rest of the NU metagame if not slightly above, having an excelling Speed tier and an immunity to all priority helping it commonly trade 2 for 1, being a great beneficiary of Glalie's Spikes to help its breaking while spinblocking Hitmonchan, further enabling Glalie's dominance in hazard stacking.
Multiple other attributes of the tier have been mentioned, such as Hitmonchan, Flareon, Baton Pass, and Arena Trap, but the two points that I have mentioned are the focal points, as they highlight what direction we can take the tier if change were to happen. Either we focus solely on the tier at hand and look at the more broken elements (Glalie) or we change NU to be more in accordance with other ADV tiers (Haunter, maybe also Glalie).
