Okay, that was a tangent of sorts. But essentially, I really do like the core classes, plus most core class archetypes. And the Magus. But not the cheesy shocking grasp min/max kind.
That feels a little unfair. A lot of people build around spellstriking with shocking grasp, sure, but at the same time you have look at their options. Shocking Grasp is the only 1st level touch spell they have whose damage dice scale with their level. Which means its the only spell that they can use with their class "tricks" from level 1 to 20 that reliably puts out damage given a few feat investments. Sure, you could make a debuffer magus that focuses on rime spell and frostbite, but its the same principle. You have level 1 spells that, given the proper feat investment, can be stretched and used throughout your character's career. Finding ways to keep them relevant isn't cheesy, its just good playing on your part.
I kind of feel like hating on an magus that uses SG is like hating on a zen archer monk. At the end of the day, you want to make your character really good at the thing you made her to be good at, no matter what that thing is.
