This choice between throughput and throughput is actually what makes speccing fun. I was doing my warlock tonight and basically had fun/fun choices. To be honest, they are pretty dull and you don't need to put any research or thought in them whatsoever. You end up doing well whatever choice you make. I sincerely hope restoration tree stays the same as it is now.
I do understand that tastes differ, but I honestly can't understand why would one want warlock-like tree. Imagine that you had something like Nature's Grace vs. Fury of Stormrage vs. Nature's Ward. There's no 'lose' scenario, you always win. You get a really small benefit to something you don't use often OR you get a really small benefit to something you don't use often. Pick a random one and you are good. Please explain me, how is it fun?
The resto tree is a balance bomb waiting to go off. If druids are balanced around having all throughput talents, then they will be underpowered cause they can't use them. If Rejuv is fine without BotG and Genesis then it risks becoming too good down the line.
I don't derive the fun from speccing. It's a tedious task that's mostly mechanical, and the fun should come from the game itself - possibly because of talents such as Eff or MG - but not because of choosing them but because of using them.
If 29 specs behave one way and this unique snowflake of a spec goes the other way, well then, changing the 1 spec is probably the way to go. Although I should probably say 3-4 specs and not 1 because that will be how many specs you'll switch between from fight to fight.
I wish we were in the situation you described, choosing between NG, FoS and NW. Those are all viable choices, all non-trivial but not spec defining. Yes, please.
