Level 110 gear on my level 50 character...

No, but progression could have been controlled a little better, IMO.
I'm not getting hysterical, just mentioning something for the sake of giving a frame of reference. Something I neglected to mention is that despite the big gaps in item level, the stat gaps aren't very notable. It does give a bad impression when the item level is jumping by what seems to be a large amount (without context the jump from 50 of something to 90 of something is large no matter how you slice it), specially so close to the game's launch.

As Craiger said, since iLvs only increase in increments of 5 at the smallest post-cap, if from the start they had just made it say iLv60 => iLv62 instead of iLv60 => iLv70 with all the stats being the same it'd be fine? You're freaking out over semantics. If items didn't have an "item level" label on them and just the stats, you wouldn't notice or care. Are people really so starved for controversy and drama?

So as Craiger said, if they just did something semantically like change what the iLv is called even though everything is the same its fine?

That's iffy. People would probably still think they're getting nerfed even if they aren't.
