... and I still have absolutely no idea what to play. Literally everything sounds awesome.

 

It's a great problem to have!

I made a list of ones I'm definitely interested in trying and I'll slowly work my way through it. Half a dozen different builds @ 80-100 hours per game, I should be right til Christmas

The usual problem with rpgs. You spend ton of time thinking about a PC, change your mind countless times, start to play and spend the rest of the game wondering if you would have liked "the other build".

For me, it'll be the "safe" paladin pick for the first run. Then I'll get bored before finishing the run and swap over to some crazily overpowered min-max build that requires excessive micro-management. Then, before I can finish that run, I'll feel guilty and go back to finish the paladin, only I'll have forgotten a choice I made or grew to dislike some other aspect of the character and so I'll start a fresh paladin. Then I'll switch to...(post carries on in same vein for some time)...and then another Obsidian or similar RPG will come out and the whole cycle will begin again.

Not really. The other build is for the next playthrough!

Honestly this is more or less what happens to me except I barely make it past the introductory sequences before changing, over and over again. I'm going to try to make an active effort to just STICK with the first character I make this time, dunno if I'll be successful in that though. I've put a lot more thought into my character this time around compared to pillars 1, so maybe I will.  

I already know what my first char will be, but the problem is that after deciding for this char I had lots of time to think about what other chars might be great.

 

And I have a second problem: While I would like to actually role play a game, my min maxing optimization obsession always wins.

I have found a very interesting idea for a build, and than I optimized it so much that not much remained of it except that it still has the same classes.

I'm sure I'll try several builds within the first week.  I had deep restart-itus with PoE 1, and I have no reason to believe it will abate given the wealth of new character building options.
