I agree with your post, however I dont think this quoted part is needed in an arpg if itemization and leveling (soft-cap) are designed correctly. The level 70 items are a bad sign to me, because I dont want to re-gear with the boring basic stats every 15 months when they throw out an expansion/level upgrade patch. Instead I want those game additions to give new items /affixes (and areas/classes/skills) so I can play around with new interesting builds. Gearscore-chasing can stay in MMOs.
Yeah, that's fair, I too, think the tiered wash out of core stats is pretty boring. It works, but it's boring.
Mostly though, if I could communicate something with Blizzard, it would be the fact that items without those primary stats aren't just "not as good", they are "not good at all". You can remove an interesting/unique affix from an item, and it could still be useful with core stats on it, you can't remove the core stats though.
And that's really a huge difference. The game would be a lot better if most items dropped had +Primary/+Vitality/+Resist All/+(Crit/LoH whatever)----and what made an item exceptional, or rare, was a unique, skill affected affix, not simply having those core stats.
So...For example.
(Normal Yellow) Primary/Vitality/Resistall/Crit or Loh or whatever/ +5% Whirl Wind Radius.
(Nice Yellow) Primary/Vit/Resisall/Crit (Maybe a little more strength)/ Whirl Wind randomly shoots an axe that does X weapon damage if you have the tornado spawning rune.
(Exceptional Yellow) Primary/Vit/Resisall/Crit (Maybe a little bump in strength and some of the resisall)/ Whirl Wind has a 1% chance on damage done to whirl a monster around and send his body out like a god damn missile, doing his health in damage to whatever he hits, if you have X invested in the hurricane rune.
So all the items are good. What makes a super rare item great is not the presence of those needed core stats, but rather, small fluctuations in those core stats (Hopefully smart enough to be a fluctuation up when a very unique/powerful specialized affix spawns) and a more interesting specialized affix that interacts directly with specific skills. Then make legendary a step above. The main thing is, there shouldn't be just junk or awesome. Many items should be serviceable (Like the regular yellow above). We should sometimes find just a yellow that's a few stat points better, with a neat little affix, that's a decent upgrade. What should be
rareis finding those yellows with the same or slightly better core stats, but a really wicked specialized affix.
