None tbh.
A) is a one trick pony that shines in difficult content vs high health mobs. But there’s not a lot of that. Also depends on whether r8 brings anything better. (That’s assuming you go int + max carve owl at least, the str variant is considerably worse but easier to level.)
B) Dievs don’t make very good str builds as carve alone isn’t enough. You should always max carve owl though. Druid transform would help with grinding as a str build, but that takes a while to get. (int transforms are not as good.)
A int variant would do considerably better, but it still not that good for solo content due to the long cd’s. Nice for parties though.
C) The paladin/pardoner is solely to turn it into a alt that makes barrier scrolls. Pardoner2 i could only recommend for a priest3 combo for spell shop. (Pardoner needs some decent combat skills.)
D) Never go oracle2, at least not yet. Death sentence is a r1 debuff that every cleric can cure (with cure). Also rumored not to work vs bosses.
Has same issue as B, better off as a int build. And diev3s usually need to fill their lack of spammable dmg skills with the last 2 ranks, oracle hinders that quite a bit. (Int based Diev3/oracle/PD is decent though.)
