-Any hero that has ever been removed was because I felt he could be better. Sometimes you try things and they don't work as well as you imagined them to be. It's not about values here, making a buff or a nerf won't do the job. Sometimes the whole fantasy, kit or idea of the hero doesn't meet up with my expectations in which case I either try something or straight up replace the hero with something better.
-I had very good reasons to nerf the Necromancer. When an Intelligence hero outdamages an Agility hero (the role of the Agility hero is DPS) then something is obviously wrong. Pair that with the tankiness provided by all Skeletal Minions and you get a hero that begs for nerfs. So don't complain about nerfs just because they are nerfs. If I nerf something I have very good reasons for it. Sometimes you may not be aware of it. Did you know that the Necromancer could outdamage the team's DPS hero before I did the nerfs in previous versions? Oh and to jump back to 2.2.7, Necromancer got some very powerful Talents for his abilities.
-How is scaling nerfing or buffing a joke? Scalings is something that has been going up and down across heroes all the time and will continue to do so, simply because I can bet I play or even observe this game way more than you do and I have insights and information regarding hero power that you do not. I will do the changes that I deem to be necessary based on my observations of other people playing the game. I did not nerf Nercomancer because I was good with him. It was because I saw another player make the Agility hero look like joke. So essentially the joke aren't the nerfs, it's your obvious distastefulness of the nerfs. Well, I make new additions, systems, abilities and whatnot all the time. And guess what? Sometimes these additions or changes require scalings to be adjusted. Sometimes it will be a buff, sometimes it will be a nerf. You simply cannot assume that I am pulling these changes out of my hat for no apparent reason. You see adjustments in the changelog to the scaling of an ability and assume I hate the hero or something. What if I have seen an interaction with that particular skill and a Glyph, Item or something else that needs adjustment? Do you know that information? No, you don't.
-I knew from the very start that there will be people complaining about Ultimates and I knew there won't be many of them, you seem to be the first one. If you loved Ultimates, unfortunately there isn't much I can do about it. To me Talents add a lot more customization and building paths to a way you play a hero while an Ultimate is an ability that does not participate in your rotation due to your high cooldown and is generally very predictable as to when you would cast it: the majority of the time you'd either dump it on big packs of mobs if it's more of an AoE ability or on bosses in the other cases. I'd much rather have a tool that allows for different playstyles rather than an ability you cast now and then in obvious scenarios and then don't even think about it for another minute or two. Ultimates are way more fit in PvP genres while they are way less interesting in a PvE environment. I'd understand if you still prefer Ultimates over Talents and to be fair I did preserve a solid amount of them into the hero kits either via levelable abilities or as Talents (Infernal, Polar Blast, Skull Split, Starfall, just to name a few of them). However this is the game that I have envisioned and so far I have gotten only 1 negative feedback regarding this addition and it's yours. I still consider it, and I knew there will be those people that liked their ultimates but it can either be the one thing or the other and I chose Talents.
Why ruin heroes you worked so hard to make with nerfs when you can try to buff the other heroes to their level?
Changing Strength scaling from 150% to 120% obviously ruins a hero, I guess... But to answer a question,
If 1 hero is stronger than another hero, you suggest to buff the second hero instead of nerfing the other. Suddenly all hero power will spike up and enemies will become a joke that you destroy with 2 abilities. "Buff the enemies aswell" you'd say. See where this is gonna go. If nerfs never happen, and adjustments are done only via buffs, you'd just start climibing an endless stairwell of taking turns buffing heroes and buffing enemies. No game can be balanced without nerfs, and you seem to be displeased with the very idea of a nerf, regardless if it makes sense or not.
