So where's a good leveling spot for sages at lvl 95+ since the guide hasn't been updated for over 2 years. I was wondering if anything changed.
Turn-Ins (Also known as TI) is what I suggest. If you got VIP, doing http://irowiki.org/w..._Turn-In_Events is probably your best bet. Just go in, find a group and spam heavens drive to make yourself useful (skill reset is free until you reach level 100, so you don't really have to worry about not having it).
Eden quests are also okay at the http://irowiki.org/w...sts#Level_91-99 91-99 range. I usually do: stapo, roween, siroma, dark priest, injustice and rybio since they are easy to get to, but it all depends on how you are geared/built. If time is not an issue, doing siromas and stapo only (non-aggressive and really weak, lightning and fire respectively) is also okay.
And if you're into grinding, magmarings might be an option. They give decent experience, but you might need two bolts to kill them, making them less effective than some. They are really easy if you have access to siroma cards though, since cold bolt should be able to kill them easily with high int and two-handed staff.
