Hi bluezlich,
i know the feeling of not beeing able to beat a minion/boss. if i remember it correctly the programmers said once they "guessed the stats babarians might have at this point"
at the end of 2012 there was a patch tuning the 45+ boss/minions down, since they were nearly unbeatable at that time...
they wanted to make another balance patch if i remember it right...
as far as the loot, there is a post here called "posing" where you can see what some people got for beating a minion/boss
i am currently lvl 99 and so far not once i saw a legendary ring or neklace

the "lucky draw" results from the 30% crit/dodge limit. so, if you get lucky in some fights you crit like 100% or (with bad luck) dodge 0%
to answer your final question, if you should give up
... well ...
as far as i can see the last time we had something done here was 2nd of february
which is around the last time we saw our administrator "Karsten"... "Chieftain" last game post is from 2012 so is "PersonalHero"´s
i personally am just waiting that one day i try to log in it says "Server not found" and everything will be gone.
until that, i will be here grinding my daily stuff, because i love this game in general

best wishes from germany
