level 17 mythic tier 2 campaign.

[Shadowscale]

In a couple days I for the first time will be starting off a pathfinder campaign at a really high level and with mythic which I've never used before.
The two ideas I had in mind, I'm currently unsure which one to roll with I'm thinking either a blight druid or the
knight of the sepulcher anti paladin as at 17 those bonuses really stack up. All first party books are available as well as deep magic. Two traits and all. I'm really taking stabs in the dark here are these both build able and how would I go about optimizing either? Race wise I was thinking either hobgoblin or surface infiltrator drow. Any and all help would be appreciated.

What bonuses stack up? I can tell you this much. Hybrid style classes do not fare that well in mythic.

I'm not taking both.

Ahhhh I forget Paizo released actual hybrid classes. If you're dead set on one of those two classes I would say Druid

Druids get some interesting wild shape stuff and a jump in spell power

Paladins in mythic seem pretty lackluster. I'm sure anti paladins are similar
