You are wrong plain and simple. We have two sources of damage over time versus a rogue (lightning shield, searing totem), poison cleanse totem combined with stoneskin totem allows us to mitigate damage while increasing the amount we heal ourselves for on top of being able to kite for a second or two through the generous use of frost shock. On top of this we are highly armored. We literally have everything we need to fight a sub rogue 1v1. Save your trinket for blind. If you have trouble its simply because you are not utilizing every GCD you have correctly, just as a good rogue does.

Now I realize this is an extreme example but my 2v2 partner (SL/SL Lock) disconnected at the beginning of an 1850 match and I was able to down a druid who mistakenly let his health reach 50% and died while his rogue partner downed my lock. The druid was simply trying to CC me but failed miserably... and I handily downed the rogue because of my extensive practice fighting sub rogues 1v1.

I say versus a equally geared and practiced rogue I win about 50% of the matches depending on stun resists (I'm Orc) and my ability to kite as poison cleansing is not a sure thing either. Occasionally I've been able to get a burst of on a rogue who's practiced on me! That is just GG...

My advice if your having trouble. Making sure to Melee at Melee range + Searing Totem + Lightning shield are your number 1 priorities when fighting a rogue. 2 is ice shocking every GCD. 3 is keeping poison cleansing totem and stone skin down. Try to cast a heal whenever you have a free GCD. It uses his energy for something besides pure damage and you may even get it off. Even try to cleanse more poisons before trying to heal if your health is not critical. Wrath of air totem is optional when fighting a rogue. If you do happen to get distance with decent health throw a CL in his face... if you do damage with CL in a duel (especially with EM) that fight is a GG! Also when your kiting realize deadly throw interrupts and slows. If you can force him throw it as a slow only you can cast a spell or two before he reaches you.

The problem with Shaman is our ability to utilize every GCD to do something useful. Work on your bindings. Make macros that simplify your button spamming. Learn to strafe kite while shocking, use your mouse for moving and steering (don't click anything! if you don't do this you CANNOT turn fast enough to fight a rogue). The advantage other classes have is having the improvements they need to make in play easily visible. Because of our hybridization, the choice is much less clear, but it is there. Just make the effort to figure out the best possible move and you could make every single GCD count. Also learning how other classes work helps immensely.
