Nazeebo as a hero has a fairly well-designed core moveset, as well as a focused gameplan. His basic abilities are intentionally hard to land, but have major payoffs when executed correctly. That said, over time his character has drifted in a problematic direction, and this was seen to in his August 2021 rework, which...
did not seem to understand what the problems with Nazeebo were.
Simply put, all the team really did was buff him. They gave every other talent he had some extra boons, just so that he'd have a higher winrate, not realizing that when a character like this has a less-than-ideal winrate, it's usually because the character kit was simply too problematic to be given straight buffs. Today, Nazeebo is generally despised in QM and other lower-level environments, and his dependency upon Vile Infection is still one of his most defining characteristics. The problem with Nazeebo wasn't that his talents needed buffing, no, but rather that his entire talent tree needed reshuffling, and didn't provide adequate payoffs for Nazeebo stacking high with Voodoo Ritual outside of Vile Infection. Part of why Nazeebo doesn't receive much compensation for acquiring stacks is because it comes almost entirely from PvE, and rewarding a player too much for a relatively risk-free part of the game is always going to lead to problematic balance.
As such, this rework aims to...
A) Give Nazeebo ways to stack Voodoo Ritual in teamfights
B) Give Nazeebo more immediate payoffs to stacking high with Voodoo Ritual
C) Reel in Nazeebo's lategame talents while still making him a lategame hero
Baseline Q changes make it impossible for spiders to ever deal damage to moving targets. They currently move slightly faster than Mount Speed (130%). This rework makes them almost thrice as slow. This ability does not deserve such an insane nerf. It currently only gets dangerous with both [Widowmakers] and [Vile Infection] completed.
New LVL1 has the same issues as the old one. Why ever pick [Big Voodoo] that became weaker with the passive bonus being nerfed when you can select [Thing of the Deep] for greater range or [Vile Infection] to actually deal damage?
[Dead Rush] granting Voodoo Ritual stacks on Takedowns does not fit its purpose. This bonus feels out of place due to other talents granting stacks from the abilities themselves. It would have been better if it made the zombies that uproot grant 2 stacks with every Basic Attack against Heroes.
[Hexed Crawlers] being moved to LVL7 with Q changes makes it very weak. There is no reason to ever pick over [Blood Ritual] that can now make you survive the impossible.
How much Health does the [Voodoo Block] totem have?
[Superstition] does not even grant 1 Attack Range. It does not deserve to be nerfed.
[Spider Colony] was not strong, the other talents were weak, especially [Soul Harvest]. This nerf makes [Ring of Poison] the only viable talent.
[Bargain with the Beyond] summons Nazeebo at the Hall of Storms... right? Because otherwise it is absurd. No, wait, it is absurd either way, as it makes it impossible to ever win a fight or push against Nazeebo due to him constantly returning at almost no cost. This talent needs at least a 60 second cooldown.
