What is the issue?
i want to enlarge the weapon enchant proc [Mark of the Frostwolf] just like
other buffs casted on me by 190% (works with legendary ring proc)

is it possible to just show stealable buffs (speelsteal) at the target frame?

Please provide any additional information below.

Use Raven and anchor the buff bars of it to your SUF target frames. http://wow.curseforge.com/addons/raven/

This is a problem with how Blizzard handles the weapon enchant procs; you don't apply the buff to yourself, the environment applies it to you.

The logic SUF uses for enlarging player de/buffs involves simply looking at the source unit, if it's equal to the player, it'll call the enlarge function. Since the player is obviously not the environment, the function is never called.
