Fire spells need a redesign
Looking at the fire spells and comparing them to other games fire spells seem extremely lackluster in terms of design and ability. IMO it’s missing things like a meteor type spell, or hydra, or anything with real flavor. I’ve noticed that while fire did get a slight buff this go around, the spells themselves are odd in the interaction, like having such prohibitively long charge up times and only a chance to do what should be basic interactions like ignite, and explode mobs. Lightning and cold have atleast fundamentally thematic skills, but lightning is really the only one that has the fundamentals, flavor, and throughput a majority of the time.
I think to fix this they need to introduce some different, classic magic skills or come up with new ones. I think in order to make fire more viable it should be baseline that enemies explode when killed and that ignite naturally spreads. These are available, but are only available through gems or a talent on the tree - but they should be baseline interactions.
Just my opinion I know the devs said that lightning was so good because it chained, but it seems like that same ability and strength is locked behind wasting tree points and support gems and the spells themselves aren’t thematically good and are way too slow to be viable. Even fireball which is a class skill seems just done wrong with how weak it is in poe2.
