Prot PvP Viability and how talents stack on SS
Out of interest and a general sense of boredom waiting for Sunwell to come out I've started playing around with theorycrafting and gearing for prot PvP. The potential to take advantage of the disproportionate scaling on shield slam seems as though it could be a very viable spec were enough SBV stacked with adequate crit. I was just wondering if anyone with more experience could offer a little insight into the spec.
Firstly I am wondering if anyone has figured exactly in what order the following are applied to a shield slam - Impale, Deathwish, 1H Spec, Shield Mastery, BG Zerker/Stormpike buff. I would naturally think that the order would go along the lines of Shield Mastery --> 1H spec --> Deathwish --> Impale --> Zerk Buff, but this is really just a guess and theorycrafting spits out much smaller SS crits than I am actually getting in BGs (predicts 3K or so unmitigated damage at about 400 SBV, with enrage in place of Dwish, and I've crit upwards of 4200 on casters).
Secondly has anyone gone to the trouble of significantly gearing/gemming/chanting to maximize prot PvP performance in the way of T5+ gear? I plan to continue scaring up 5 pieces of T4/5 gear for the SBV + Agil/Str as well as several key pieces from ZA/Heroic Badges when the next patch hits and I'm basically wondering if this is worth bothering to do. If anyone has had a serious go at maximizing the potential of prot PvP, what results have you had and how much have you geared.
Cheers to anyone that can offer decent insight for me, even if the entire idea of legitimate prot PvP may seem a tad retarded.
