sadly your right.......
the intent was to make heavy armor good in the game by giving it the higher PRR.
However because of the PRR curve you can still attain 100+ in light compared to
say heavy armor its around a 5-9% damage reduction.... of which you tend to
lose a higher capacity for dodge % and then of course lose any chance of evasion.
I just TR'd a 18/2 pal/fighter heavy armor user into a 18/2 fighter/mnk light armor
user and I hit 112 prr 25% dodge evasion with 40+ reflex....
There is no comparison in tanking ability In EE's sadly.
My survivability has gone way up with my only sacrifice being 20-30ish ac and 6% PRR.
AC needs a little bump
PRR needs a better curve and heavy armor needs a base number of starting prr no matter the level of bap or player.
Heavy armor needs to give natural hate%
