not all ac affecting skills spells matter I think. I don't believe faerie fire slammed it but berserk sure did.
This is not true.
the ac from gear and skills/spells is all that counts towards the legacy.
This is true
putting up spells may push you into the gates threshold but you only get messages when putting on and taking off eq
This is true
gates sure as heck does work, the major problem though is that people tend to overgear for it then suck.
this is opinion
further alone gates is not a big deal but when you stack it with some other dam redux it becomes nasty, svirf villagers take lower case damage or mutilates mostly with it.
this is false. Gates on its own can get you insane dam redux if you know how to gear it.
Some thing to add. New armor changes fucked gates.
