Ranger Specific Buffs & Stacking
 

How do ranger-specific buffs such as Call of Earth, Strength of Nature, and Call of the Predator stack with standard buff classes' spells granting similar stats (DS/AC/ATK) work? Are there still times if I have a healer class in my group that I wouldn't want to cast these as they'd be sub-optimal?

There's a bunch of buff stacking issues you need to learn.

Strength of Nature: Overwrites Grim Aura. Overwritten by monk epic. Blocked by Divine Strength. It's good on rogues. Not monks.

Call of Earth: Blocked by Coldain rings 8 through 10. Has stacking issues with Speed of the Shissar (Enc Epic). Stacks with DS and coat buffs. Doesn't stack with DS potion.

Call of the Predator: I think this stacks with everything, thankfully. Good for monks / rogues.
