Spell damage through the campaign and early maps needs to be looked at

I have leveled 2 spell casters so far, didnt really use any twink gear just to get a feel for different skills and i have to say the damage is either bugged or something is off. Like no matter what supports you stick in there and even if you upgrade your weapons with the highest + spells available at the level the damage is lacking.
I have played this game a lot and also poe1 for 4k hours and this is not acceptable.
I feel spells need to get a major damage buff, and also the pay off for comboing them and use the infusions needs to be way bigger. I dont really know how or by how much this needs to be changed but i know the current state of spells is not it.
