Yah it's blockable but not evade-able, I've tried tanking as PGL with +100 evasion on gear, only evasions I ever got in a few runs was only during 1st 15% and nails phase and even that was almost only when featherfoot >.< Overall, while PGL can tank it, unfortunately isn't effective at all since you take much more dmg than others, even with FoE up, and to do good dmg combos you would need to move to the side and well, a tank moving to the side in ifrit can cause all sorts of problems... So is better to use a MRD or GLA instead. =( PGL can do really well as DD on ifrit anyway since that's what we are now, full out DDs =/
