Personal preference? More push power than most other mages?
It also quite depends how much they nerf the spiders. Even if they reduce their damage per hit by 4 (or roughly 10%), they’d still have the potential to deal 1155 + 4% damage (without Vile Infection). It will still have the potential to 100-0 squishies with Vile Infection tho.
So I think that a more drastic nerf would be needed. Like reducing the spider damage from 38 per hit to 30, but also increasing Jar’s break damage from 50 to 75.
This way his Q will be on the edge of being able to 100-0 heroes with 1300 HP. It will theoretically deal around 1328 + 4% damage, but it will deal it over 10 seconds, so the hero’s natural HP regen should prevent the hero from being 1-shoted.
Even with this nerf, it will be pretty powerful. It will just REQUIRE more out of you than just hitting a single jar.
They can also increase spooder’s damage to non-heroes. Or perhaps increase the Q slow duration to 2 or 2,25 seconds.
Or maybe the best thing they can do would be to replace the Q quest reward from giving spiders 30% increased damage to increasing the Jar break damage by 100%.
When we compare my 1-st suggestion to my 2-nd:
1-st: Jar deals 75 damage, spiders deal 39 damage per hit (with quest completed)
2-nd: Jar deals 100 damage (with quest completed), spiders deal 38 damage per hit.
Mathematically, the damage is the same. But with the 2-nd option, more of the damage is upfront, and it’s more reliable.
Also, with the 2-nd suggestion, his other builds will not suffer too.
