Featherfoot should be modified to be useful at endgame.
So my friend and I were doing titan ex as tanks and my friend (war) asked me (pld) to blind titan with flash before mountain buster so he could featherfoot and see if the combination of the 2 would make him reliably dodge it.
It did not. So we were talking about how featherfoot should be adjusted to be a reliable cooldown at endgame, similar to bulwark on PLD, not completely reliable but good enough to be used as mitigation.
The problem we struggled with was that if you made it strong enough to use at endgame it would be too strong in dungeons and low level content. In the end the idea we settled on was to make featherfoot work similar to sentinel from FFXI, have it start off strong and weaken over time. Perhaps start at 60% dodge rate (80% for the enhanced version) and decrease by 10% every 3 seconds. So 60-80% > 50-70% > 40-60% > 30-50% > 20-40% > effect wears off
