Some time has passed since the massive nerfs to Undead.
The obsidian statue nerf affects all Undead units and heroes with mana, even those which are not often used in competitive games because they are too weak. Best example: Necromancers, The Crypt Lord and the Dreadlord.
Meanwhile other races also received nerfs, but most importantly, buffs in areas to allow new strategies. But this has not happened for Undead, so they need buffs for underused units and heroes to allow new strategies aswell.
After all this, we have to ask, where is UD getting anything new and exciting? You immedaitely scrapped the +30 HP for Ghouls, even before you added more and more nerfs. It is only fair to keep the +30 HP for Ghouls now given the fact that you piled on more and more nerfs for UD.
A big side effect to the statue nerf is that Dreadlord and Crypt Lord will be played even less, since these strength heroes heavily rely on mana for spells and have poor mana regeneration.
Both heroes have a passive (vamp aura and spike carapace) which is underhwelming. Vamp Aura could have been useful if you had kept the +30 HP on Ghouls, which you should have given the amount of nerfs UD is getting. And spiked Carapace is in the exact same spot since you buffed spiked barricades for Orc, thorns aura and ring of protection. All these things got buffed but spiked carapace was not, even though the effects are the same.
Please consider buffing mana regen for Dreadlord and Cryptlord to compensante for Statue mana nerfs. Please improve spiked carapace for Crypt Lord. And please add the +30 HP on Ghouls so that Dreadlord + vamp aura will be a viable choice for the first time ever.
Its about time that Necromancers get a rework. Mass Necromancers + Wagons is a horrible strategy thats not fun to play with or against. Infested Terrans were removed in Starcraft 2 because mass summon units are simply bad design. Swarm hosts were also nerfed because playing against mass summoned units is simply not fun and its very hard to make it fun.
I am sure there are now more than a hundred pages of suggestions on the forums, on reddit, on livestreams, on how to make Necromancers a viable support caster. Please give us the rework we have been asking for for years. I am sure the community will do all it can to make the rework better and fun.
We already tried it once and I believe switching around the spells and adjusting numbers is key. Raise Skeletons should be less about massing weak units. See this suggestion to double the stats of Skeletons but greatly reduce their numbers. No one is asking to make this unit overpowered like the last rework. It should be a viable choice, which it is not, because UD is forced into a fast tier 3 every game because UD has no dispel on tier 2.
Look at this, we had another discussion about Necromancers, but you ignored it sadly:
Its about time that Frost Wyrms receive a buff to be worth using. We haven’t seen a single Frost Wyrm in so many competitive games, even after they became more accessible.
We have suggested reduced cost and reduced stats and increased attack range. Their attack range is too low, everyone is using ranged units nowadays due to ranged unit powercreep. Frost Wyrms are taking way too much damage before they get many attacks in. So consider making them a cheaper unit with less stats but more attack range so that they are less of an investment.
Simple suggestion: Increase Frost Wyrm attack range by 100. This is the exact change that made Orc Headhunters viable. Do this and the unit can be useful.
Please consider reducing Abomination collision size and increasing their turn rate. This unit is very clunky. The big problem is its collision size, You see, unlike Bears and Knights, you cannot have a frontline of abominations because they occupy too much space.
Reducing their collision size would make it so much easier for them to get in melee and attack. Instead, they are mostly damage sponges and spread disease cloud, but they cannot attack often.
The mana nerfs on statues alone are a massive -33% nerf on mana for every single UD hero and caster. You cannot justify nerfing a race this much and not giving them anything worthwhile in return. Please do not treat your playerbase like this.
