Given the current “bottom-tier” status of Human in this patch, it’s really time for some buffs. I think the Archmage definitely deserves one.
The Archmage has long been at a disadvantage against Orc. Against Undead, he’s almost useless in the late game—basically just a walking Brilliance Aura / item carrier, and an easy target to get picked off. In the current version, Human gets completely crushed by Night Elf at equal skill levels.
This situation is closely tied to how the Archmage’s other abilities are extremely weak as a “trade-off” for Brilliance Aura. Water Elemental is arguably the weakest summon in the game, and Blizzard is a mediocre AoE spell (a fragile caster that has to stand still to channel it). Meanwhile, after the aura nerf, Brilliance Aura is no longer essential—especially in matchups like Human vs Undead where you don’t even go for arcane Sanctum. In fact, the Archmage can even be replaced by the neutral Firelord.
So it’s definitely time to buff the Archmage. Considering buffing Water Elemental would obviously change hum vs ud, so I suggest buffing Blizzard instead.
Specifically: increase Blizzard’s damage from 30/40/50 to 30/50/70, and make the duration fixed at 8 seconds.
This change would mainly affect the currently skewed Human vs Night Elf matchup, and would have little impact on the other two matchups. First of all, the current damage scaling (30/40/50) is clearly too low. A 33% scaling for an AoE ability is almost unheard of—only Chain Lightning has similar scaling, but it compensates by increasing the number of targets, so its total damage scaling is actually higher than 33%.
Also, the current duration scaling (6/8/10 seconds) is kind of awkward. A 10-second Blizzard is only really useful for hitting buildings, while in most cases the cooldown doesn’t justify needing such a long duration. So fixing the duration at 8 seconds (or even 7 or 6) would be more reasonable, and the damage scaling should be improved accordingly.
Overall, this buff would only benefit game balance. Hum vs Ne (or maybe a bit vs Orc) gonna be a bit easier. Nothing else changed.
