i have watched this a fair few times xD i really really like the idea of a warlock tanking spec, i know you will all be like "pfft a clothie tank" but think about it, we have searing pain that creates a shed load of threat, of course it would have to be demonology, no other spec fits it.
It would be quite easy to change into a tanking spec, change Demonic pact, to increase your threat instead of spell damage, change demon armour to increase threat and increase the amount of armour it gives.
make the new demon soul thing make the VW reduce damage taken for a few seconds, make searing pain instant cast, that way you only have to cast immolate at the begining of a fight, use fel flame to keep it up and use searing pain (that would probably have a short CD) and dots for single target, for AE tanking jsut use hellfire, ofc without the self damaging thing
i could go on but im lazy and its nearly 1am :P what do you think? i personally would love it, im sure like 90% of people hate it but oh well, jsut throwing it out there
