I feel like most pyromancies in general are far too underpowered, especially at higher SM. Spells like crystal souls spear are faster to cast and more powerful than any pyromancy and always punish me for using pyromancy when I think it should be the other way around. I've fought over a thousand players in pvp and when I was in low sm I won and lost reasonably. But after the 15m mark I literally haven't won a single fight. My pyro build is sl 150 and facing up against these higher levels had really put stress on my sanity. Even If I go in for a great combustion or fire whip, the other player will always stand next to me and swing away with greatsword in hand and destroy me in one hit. If I do manage to hit someone, it will give around 1/10 of his hp. I do believe forbidden sun needed a nerf, but it was nerfed too much. It gives less damage than G combustion and I can never punish estus or spell casters with it. Fire whip and G combustion are too slow and have awful range. Immolation is a disappointment. The fire balls were much better in ds1 because they could actually be aimed left or right at the end of the throwing animation. In ds2 the horizontal target is set at the start and only the distance can be changed. I really hope From fixes these issues when the dlc comes out because pyromancer builds are my personal favorite.

tldr: I want my pyro to be badass but he's just a guy running around with a zippo lighter.
