Is there a difference between Tyrant gear other than just the name?

As everyone else has said, the only difference is in the name and class, enhancement stat gains are the same all around, regardless of what class it's actually for.

So, if one were to plan on transposing say, a Tyrant cape onto a Sweetwater item, you could just scroll/pot the cheapest one and still be fine, minus wasting a perfectly good, scissorable Tyrant, that is.
