The shaman talent Dual Wield Specialization isn’t applying hit correctly. This talent is broken, you only get hit from this talent if you put points in it while dual wielding and as soon as you log out and back in you lose the hit% from this talent.
I have tested this on the PTR on my level 60 enhancement shaman on a level 63 Boss Dummy. When i select this talent with 3% hit on my gear and getting 6% from the talent i am initially getting no misses on stormstrike and windfury hits which are both special attacks (yellow hits) in TBC, meaning they cannot miss once you hit 9% hit. But as soon as i log out and back in i lose the hit% (also shown in my character stats with the addon CharacterStatsTBC). When testing on a dummy my stormstrike and windfury hits are missing after the relog.
Before testing this myself i saw another post about it on reddit but i couldn’t find anything about this bug on the wow forums.
The only two ‘fixes’ currently is to either never log out or reset talents before each raid / dungeon which might be a hassle to say the least.
