Just to elaborate more on what others have said. The rampert cuts down wings to almost nothing. Only real test I have had.
The sentinel does seem to lose effectiveness over time. Most likely has a set amount of dmg it can absorb before it starts to diminish. The enmity boost is quite big. Idk if I can properly say how much bigger, because I have capped guardian. It seems to put me a lot higher on the hate scale when used(do a lot of tanking with nin/brds and defintely saw a difference with /war haven't got a chance to /nin anything big yet since update).
Overall the changes are exactly what was needed to make pld not so sub job dependent.
