Melding question

[billydata21]

So each stat has a cap on an item based on the item slot, the item level, and the actual stat(Spell speed vs int). The base stats on an item before melding count towards this cap.

I thought that was the reason. I think it's confusing so many people because it doesn't say "Stat can't upgrade anymore". It says something like "The item lvl is too low" which makes no sense. They need to change the wording on it.
