Re: Which build?
Not if you want to avoid single-tree builds. :crazyeyes:
... the TK/ES portion of that build is entirely defensive, so you'd have very few offensive options against cold-immune monsters. If you're not willing to go with a pure-Blizzard sorc, I don't see how this one would fit (because it's basically the same cold-based sorc, except with less power and more defense).
In regards to the others, it basically boils down to which you think you'd prefer as a "primary" tree. The Meteorb is primarily a fire-based sorc, the CL/FO is primarily a lightning-based sorc, and the Blizzballer is primarily a cold-based sorc (although this has the strongest "secondary" of the three).
Honestly, if one sounds "more fun" than the others to you, then that's probably the one you should choose... the other differences are minor enough that I think "fun" is the biggest factor in making a proper choice.
That said... Each will work very well against Pindle.
The CL/FO sorc doesn't have the consistently high-end damage on one element that the others have (Lightning/CL have a
very low minimum damage, and FrozenOrb is strong but not super-powerful), which is why it's a little slower against Meph (and other creatures with very high life). The others will consistently maintain higher damage in their "primary" trees.
But, as I mentioned, CL/FO has possibly the best crowd-control of those three. Chain Lightning and Frozen Orb are two of the best crowd-control skills a sorceress has (along with Teleport for mobility and Glacial Spike for freezing).
If you think having a little more of a defensive focus is a good idea, then CL/FO might be the build for you. The 'Achilles Heel' of a CL/FO sorc is that the lightning spells require a lot of mana.
Meteorb... as I said, it has a well-deserved popular reputation as the "best", because it can build a very strong offensive attack in the fire tree, and still has a strong backup attack in FrozenOrb (that does very well with crowd-control). Fireball is usually the primary focus, with Meteor being used on act-bosses (it spanks Meph) and other slow-moving targets (Meteor's a little harder to aim). As I said, it's a very well-rounded build, capable of going anywhere. There aren't any significant 'Achilles Heels' to a meteorb, except possibly:
Generally though, throughout the entire game, Fire Immune (FI's) monsters are the most common immunity that you'll encounter. FI's are probably ~5% more common (overall) than any other element, which doesn't sound like much, but then again, when you face thousands of monsters... also, all of the best MF areas have some FI's, while there are a few places where a lightning or cold sorc can go and not encounter many monsters immune to their "primary" element.
This build will do very well against Meph & Pindle, and be very versatile throughout the game, but if you think you might eventually migrate into Baal or Pits runs, it might not be the best choice because you'll be getting into more fire-immune monsters.
I don't see why you ruled out a Blizzballer, so I'll give it a summary too. Even without full synergies, Blizzard can be a very strong spell. You can also mix in casting Glacial Spike or Ice Blast to freeze monsters within a blizzard, so this build is quite safe if played "well" too. Blizzard is great against Pindle and Meph. On top of that, Fireball is a strong and fun backup attack (because of the aforementioned FI's, I actually prefer Fireball as a "backup" instead of a "primary").
The 'Achilles Heel' of a Blizzballer - for me - would be the supplementary cold-based attacks you have available, and how they interact with Blizzard. Glacial Spike is like a cold-fireball, hitting multiple targets and freezing them in place. Unfortunately, its damage sucks. Ice Blast has much better damage, but the missiles move slowly across the screen, and it can only hit one target... On top of that, both of these spells can freeze a monster in the midst of a Blizzard - which sounds good, but sometimes no Blizzard (no matter how many times you cast it) will ever touch that monster while it's frozen. I find that very frustrating.
So, there you go. I don't know what else to add of my opinions on the subject... I definitely think the "fun" is the biggest difference between those 3 options, and only you can determine what you think is "fun".
Preferably Pindle/Meph/Baal. One of those three. Of course, after mfing, I would like to possible beat the game with her, but that is not really my goal. Now onto the question: Which sorc build would allow me to perform this with the least amount of worries? There are quite a few sorc build out there that lead me to insanity in choosing which one to use! AHHH! I am going to be playing solo singleplayer the whole time with this beautiful sorc. I do not have any good sorc gear at the moment, so I wouldn't be able to mule trash over to her to help her.
