Nerf restoration shamans

I just finished an 20+ minutes long kiting session of an resto shaman. I had him on 20-30% nearly 95% of the time, but each time he popped out his water shield (apparently no cooldown) and got back mana which I drained constantly with viper sting. So, we ran around the columns for this tiny session and I drained him and damaged with pet and all along when he got that little mana, he healed up. My mana drained itself even with aspect of the viper on and there was no way on earth I could've nuked through his 10k + armor which every arena resto shaman seem to have.

I'm not probably the only one with this opinion. Resto shamans are impossible to defeat in 1v1 (arena, to be precise) as a mana-user, since they can run around the columns forever and regain enough mana to cast off that 2k lesser healing wave, which mitigates whatever damage you could've ever even dealt to that coward. And then he casts off a couple of flame shocks every now and then and runs behind pillars, until the class which can't heal, will die. Kind of like trees die when they get old.

The next couple of comments from shamans representing this class will probably now wet their pants and start screaming "OMG LOL HNUTER CLALLING FOR NERF OMFG" or "L2PLAY", but I can assure you, I don't give a flying f*k. You can scream all you want, you can flame me all you want, but this class requires some kind of a nerf. Either be it removing shields or increasing healing costs or nerfing water shield to pve-use only, but this is just plain, f*ing ridiculous.
