InEffect: Never gets transformation
We usually get a good laugh out of babby beginner powergamers like you. You're JUST at that level where you've discovered that a 20 Strength Half-Orc Barbarian isn't the most powerful thing in the world, but you're still so possessed of wrongthink and misunderstandings that it'd be adorable if you weren't ALSO a D&D player and therefore have your head two feet up your rear in self-assured smugness.
I looked over your godawful builds. They're fun to think about. Fun to imagine at the end of the game when everything unlocks. But when you become more seasoned, you understand that you don't build for endgame. You build for play with a mind toward endgame. Everytime you squeal about trading off a level 13-16 ability with limited uses for making a build stronger for the first 15 levels to get there, it just exposes your ignorance.
InEffect: never gets anything useful out of saint
It gets everything useful out of Saint. L2play
InEffect: what duelist does there is beyond me entirely
I know. I've seen your beginner builds. Here's a tip for you. Sword Saint AC and Duelist AC? They stack. You double-dip Intelligence. I could go into Riposte, Precise Strike and everything else, but those are a bit too advanced for you.
InEffect: that will have 14 BAB at 17 with no way of fixing it
*nosepinch* Rogues and Magus have the same BAB progression.
InEffect: gimped saint that won't get to fighter feats
You get those at Sword Saint 7, which is what I said to take the class to. I really shouldn't have to mollycoddle you this much.
InEffect: saint13/vivisectionist1/AT3. that at least would have transformation to show for his efforts by the end of the game
It's about feats, not Sneak Attack. Again, I explained this to you. Vivisectionist is nice, but you don't get the free Weapon Finesse and Dex to Damage feats. Given the build requires a deep dive into the Crane Style and a number of other feats, getting two free, AND several dice of spell-stacking sneak attack makes the Rogue the superior option.
Anyhow, good luck with your next 20 Str Half-Orc Barbarian build!
