Just goes to show that you can go a long way by writing eloquent posts.
So if I understand Worshaka's argument correctly now, it's that
in his personal experience, he is doing good dps compared to the rest of his guild because he doesn't care as much about dps meters and chooses to focus more on avoiding things that will kill ya in boss encounters. An interesting proposition, but I fail to see how that has anything to do with shadowpriest issues. Seems it has everything to do with your personal playstyle.
Furthermore, you
can be quite aware of your surroundings
and dps to your full potential at the same time. If we have to bring up anecdotal evidence, I'm not doing too bad in my guild either. I usually place quite high in any fight that requires some complexity, and I'm not dying either.
I also notice that even though I gear up faster than most others in my guild, I'm falling more and more behind them in terms of dps. You may argue that it should be enough to address scaling problems in later expansions, maybe by increasing some spell's damage by x% or some other temporary fix.
It is my firm belief, however, that scaling problems should be nipped in the bud as soon as possible. It's really quite disheartening when you see every new piece of gear dropping in an instance and know that it would be a much larger upgrade for the mage beside you.
No. Making dots scale with haste is the best thing that's happened to us in quite a while. I don't know if it's enough yet, but it's certainly a big step in the right direction. Better scaling!
