As FoF is an enimity tool, you want it always on cool down, rampart is a fairly weak mitigation skill, so its nice to use it on cool down as well. In dungeons, you'll find this means you almost always pull with these two buffs, and as you spam through on a boss, you'll keep re-using them for maximum up time.

I use this even on Titan HM, after all, we aren't gonan hit it for much anyway so no need to save FoF for heart--just switch to sword oath.
