Quoted. I'll probably be the only one that agrees with you here.
I think all who vote for bad and very bad will agree:D
Lets see how that whole PvM revamp will work on beta - if it will be bad or most ppl wont like it I think there wont be any problem to come back to old system(imo any revamp will mostly benefit big guilds and experienced ppl who can adapt fast:D so I wont be suprised if lots of ppl who were for that change will suffer later:D).
When it comes to AI mobs in generall its only a minor setback till you learn the new tricks - if you want real challange go PvP thats where you got real Intelligent opponent - the core of HB is its PvP system when it comes to PvM there are lots of games who basically got only that...
