Btw if you double elemental damage, mage staffs are gonna be really great

And no 90% of the existing talents are not small buffs.
Guerillia - double damage from stealth.
25% elemental resistance
backstabbing
Even zombie isnt as small as you make it out to be, it actually is huge.
Those DEFINE the way you play, your very options. Just like GC or Lone Wolf or leech.
90% of the existing talents are too weak is what should be said. There is nothing wrong with very strong talents, that alter your gameplay in very unique ways. Some of them might be over the edge (e.g. leech), but those are the baseline in terms of how much power they should give you, not the weak ones, that nobody in their right mind would pick.
