There has been talk about building class guides incorporating the new pathfinder classes. Overall most of the same advise applies, but there are difference. The sorcerer has remained mostly the same in terms of spell selection, which is by far the most important facet of the character but pathfinder has incorporated bloodlines, which serve as a group of choosable class feature that give the sorcerer a much needed reason to not take a prestige class, as well as expand the flavor. I wanted to get public input on people's preferences.
here's my take:
Aberrant- while this has an odd flavor it a fairly good bloodline, especially the long limbs power dealing touch spells at a range is great. It has some decent spells too.
Abyssal- The summon stuff is cool, the gishy stuff isn't 50/50
Arcane- The is the default bloodline, so it's a good thing it worth taking- it's pretty great all around. Good spell list, choosable skill, almost decent feat list and generally useful powers. If you aren't sure what to do take this.
Celestial-meh- it has some dive spells you can't get otherwise, which is cool. The flight, while limited, is given early enough to be a draw. lots of resistances. Ascension is good. but the healy stuff is weak. over all you won't be gimped to use it.
Destined- I don't like it. it seems to be divination based, and the new diviner wizard is amazing and this one isn't so...yeah it has boring flavor and its not that enticing. If someone noticed something I didn't tell me. Because this one looks like the worst bloodline.
Draconic- solid, but not great. I'm not crazy about aligning myself with a particular element, but this class has other things going for it. like class skill:perception. nice. And wings. I'm a sucker for wings (especially buffalo) though it does come in rather late. My real problem is that three spells are wasted on form of dragon.
Elemental- I like the flavor but it's bad for the same reasons elemental savant are bad. If you are made of fire and fight a fire creature, you're boned. I'd choose air though if I took the bloodline (electricity and flight are better than the other energy and movement combos, seriously who needs a swim speed without waterbreathing?)
Fey- I like this one a lot, but probably more than it deserves. It gives a decent skill, and it spells are pretty good ( i really like irresistible dance and shapechange) It has some good powers and some not so good ones.
Infernal- It's good, class skill: diplomacy is a good start, and corrupting touch is cool. That said, if you hate enchantment you won't like it. But I do like enchantment. but I don't like meteor swarm. still better than abyssal.
Undead- Pretty good, but I'm not sold on there sorcerer-necromancer. leave it to the clerics. but I'd be happy to be proven wrong.
I'd love to hear what other people think.
