i actually really enjoy the idea of stances. however there should be a severe negative side to switching between them, such as a high force cost, or long interruptible cast time.
i'll make a comment on each of the stances presented.
Healing Stance: it definitely should have a 'cannot happen more than once a second' effect because of all of the healing ticks sorcs have, however only 5 force? it would have to proc on cd 10 seconds in a row to just about equal 1 consumption, pending on set bonus. hell, i'd still take it, some is better than none.
Lightning stance: the 10 second cd needs to transfer as well, way too much aoe damage potential without it. i like the additional proc chance on lightning attacks.
Madness stance: with full madness CL isn't even an option, i'd suggest having the new buff work on FL, DF, and Affliction. as far as single target dps goes, giving madness more energy options won't increase dps. some suggestions for dps increase: the stance lowers the cast time of FL by .2 seconds. Change the duration of the increased CD talent from (1/2) to (2/4) and change the proc in focal lightning - force lightning from (10%/20%) to (15%/30%). Have Lightning burns apply a 10 second 20% armor debuff.
hybrid users would be saddened by this change however.
also as a personal preference, give sorcs the option to not have to use lightsabers! :3
My ideas were pretty much just a basic framework of something to throw at the Devs. All the stances should be high enough in the tree that a cost for switching wouldn't really be needed seeing as your going to have to throw a lot of points into each tree to get 2 and give up a lot just to try to hybrid.
As far as your feedback on the stances themselves. I agree 5 force every second isn't a lot, but its also added at the cost of nothing so free force is free force imo
I tried to copy the text of the original skills as close as possible, sorry I missed the cooldown for lightning but totally agree it needs to stay.
With madness I meant for it to be on Crushing Darkness not Chain Lightning lol. Im not going to really go into your response as Ive never played the tree so don't know much about it however I will say that if giving ideas we should try not too add damage AND resource management into the same skill if tweaking the tree. The idea is never to make us OP but bring us closer to the performance of other classes. I wouldn't want us to be the next sniper or mara, merely considered more viable.
The idea of buffing classes has been a very hot topic on my guilds (E) TS with myself and a few others and we have all come to the conclusion that the best way for the Devs to go about bringing the reguard classes up to the level of other DPS classes would be to make small improvements over time. That way if the buffed class was to get to the point of overpowered you would only have to revert back to what the class was 1 or 2 buffs before instead of just hitting it with the nerf stick.
