With regards to regen vs. stun immunity; if you don't mind playing as a blob. It really depends on why you are playing the class, i play a shaman because i love the versatility and i would argue we are the most powerful class through velious in terms of soloing (challenged only by maybe an enchanter). Having said that, regen is more useful if you're in a full group where you are less likely to be taking hits unless you screw up and slow a mob too early or your monk brings a massive train. Stun immunity is infinitely more useful solo or in duo/trio situations however, which is where i think shaman really get to show their true power.
