EQ says: that ogre Beserkers are immune to frontal stuns and have higher melee stats.... is this still true in the 90s and 100s? Please advise and thank you
Yes, frontal stun immunity works at all levels. The higher base melee stats are irrelevant once you're past the low levels and reasonably geared.
if your role a heroic character though, do you get all those frontal stun immunity AAs? is this advantage moot after a certain level? Thanks again
Yes heroic ogres get the same benefit. As far as I know it's always a useful benefit for non-tank ogres since they don't otherwise get stun immunity AA's.
IIRC Beastlord was the only class that has no stun resist AA's and could be an Ogre. Also, that is immunity to frontal melee stuns, spell stuns come right through
