Rogue trainers not working

I had visited few rogue trainers in different places and no one of them working. I clicking many times on train me, but nothing happening. Am i only one who have this problem?

You dont have to visite trainer to learn skills in mop.

So why these trainers are there?

Purchase Dual Talent and reset your glyphs/talents if you have no powder. Plus it would feel weird if our trainers we used for like 7 years were gone.

Ok, thanks
