I wrote this post to reply to this thread http://us.battle.net/d3/en/forum/topic/7253855835
but its full so I'll post here instead since its my suggestion on how to improve the monster power system.
Hardcore-related suggestions1. Make us fear for our life again.Right now, top level characters have almost no way to die except by DC.In d2, there were scary places/monsters that made even top players fear for their lives.Add those places/monsters in, add in rewards for fighting those monsters, thanks.
I am also a paragon lvl 100 hardcore barb (EU) and I agree that hardcore has become less enjoyable now that monster damage is lower. A few patches ago I had to min/max my defence and plan ahead before engaging any elites in Act 3. Now i just rofl-stomp MP4/5 with half my focus on the game and the other half watching streams/TV/forums because i can pretty much not die. (doesn't sound very hardcore or fun:P) Increasing MP won't help since its not efficient at all for farming.
Monstor powers were a good idea but i think the scaling design was not ideal. Right now every character has 1 or 2 monster powers where they will farm most efficient depending on dps, so in reality there are 10 monster levels but not 10 real choices of how to play only 2-3. The monstor power system should reflect what the game was like before when each act got harder but you also got the chance for more rewards in a higher act so it was a real goal to strive for. If they increased monster damage and also loot drops/MF alot more with higher monstor power then playing at higher MP becomes a real goal to strive for and defensive stats would also help you farm better making gear choices even more interesting as well as skill choices as you need to consider defensive stats and not just max out dps.
The MP design i mentioned will also help counter-act the broken-ness of barb ww spec since this spec's effectivesnesss scales too well with higher monster health and would be less effective agaisnt against mobs with higher damage but not exponentinally higher health. It would also help caster classes scale at higher MPs since part of their defence is killing something faster and they would be more effective vs mobs with double damage and triple life rather then 1.5x damage and ten times the life.
IF I or anyone else has the best gear in the game wouldn't it make sense that farming MP10 should be efficient because you can take the high damage mobs deal and do the required dps to kill stuff for lots of loot. Current system seems very flawed since with with the best gear you can go MP 10 where mobs do like 0 damage have huge amounts of life and drop low loot for time spent killing them while farming low MP is the most efficient even it its barely faster with the best gear than for someone with low gear and movement speed increases who is farming MP0/1.
Imagine how amazing and fun it would be to crank up the MP to fight hard mobs for a challenge and for lots of loot. The only practical reson to do high MP now is for keys or ubers but not farming which is basically what Diablo is all about.
