It's a tough one. My guildies, especially my Karazhan group regulars, are used to my threat generation and know to go easy on the accelerator for the 4-5 seconds that SoV takes to get ticking over. If there' s someone a bit hair-trigger on the night i'll splash a SoR in at the 1st chance I get, but consecrate usually does the trick. 2 things make me hesitate in reccomending this method to everyone, given that SoR is a simple and effective aggro gain:
1. The biggest difficulty is the need to react to the threat level generated, the cooldowns running and the total stacks of SoV on the target. It causes a dangerous amount of tunnel-vision and means I have to have total confidence in the rest of the party to be getting on with whatever they are doing.
2. The major flaw in this method for me is that AS misses from time to time, and the SoC that i have ready to judge needs to be traded for an SoR and judged fast. It's rare but leads to the odd messy pull that is a breath away from total chaos.
However i've found that juggling SoV with SoJ maxes out my threat potential so the DPS can just go nuts. Also the joint effect of even just 3 stacks of SoV and consecration means that in knockdowns and stuns the aggro keeps on building nicely. Overlaying SoJ procs with the SoV debuff at full, switching to SoV till renew (or 2 sec off debuff fading), Judge SoV and start SoJ again keeps the aggro engine ticking over. Improved judgments means i can work it into a more responsive casting sequence, all depending on the success of the SoV procs.
So if SoV stacks are not building fast. SoJ JoJ SoJ/SoV (depending on the state of the aggro list) and let the SoV stack up. If the SoV stacks just fail to materialise SoJ is a great parachute as long as it's nipped in the bud early.
