yet you disregarded my entire post when i did mention a resil stacking shaman in the very first sentence. i have a feeling that either you were being subjective or you hate reading wall of text.
I disregarded your entire post because you used Zmirnoff's burst PvE dps (including a potion) as a basis for a PvP arguement/point. You do realise in order to get those kind of numbers he has to be lucky with a windsong mastery proc and have all his cooldowns up, right? I don't see how that's an accurate representation of what damage someone would do in an average PvP situation.
How would he survive with about 50k hp + 40% resi (~83k EH) and no insignia? I know Ice Barrier would help on top of that, but I highly doubt he'd survive long enough to get all his DoTs up on (and kill) an enemy (or several) that are capable of CC'ing, interrupting/silencing, healing, popping defensive cooldowns, dispelling, using an insig, or even just bursting him down. Remember, he could only kill a resi stacked resto shammy (Xipe) with
all his cooldowns and no use of dispels/insig.
I'm not saying the rest of your post is wrong (I actually went back and finished reading it, and yes levels higher than 80 could be very powerful if geared right), but it would've been a lot more credible if you'd done tests on a PvP geared (plus the 409s) mage and came up with your required EH numbers from that value instead.
