idea to make thousand sons better

[Lord Asvaldir]

The first option is way too powerful, the second just doesn't make sense-Tzeentch doesn't save his sorcerers when they draw the attention of daemons through perils. 

[tdemayo]

Another design questin probably worth asking: what role do we want Thousand Sons to play? Do we intend them to be a support unit? In which case, we are free to make them specialized and fairly expensive. (Think wraithguard or terminators.) Or do we intend them to be basic troops, perhaps as part of dedicated Thousand Sons warbands? In that case, they need to be cheap enough to field in bulk and have enough options to fulfill several basic functions.
