It's important to separate the problem from the solution. I think most people who posted in this thread will agree that there is an issue with the classes being balanced poorly.
Class balance is fairly complicated, especially when we haven't seen several of the classes and don't know in what ways Larian is going to deviate from the rules that might further throw that balance off. I would love it if they had actually attempted to present us with a RAW version of druids to start with. What we have now isn't that far off from RAW, but the few differences (i.e. mechanics of activating concentration spells, wild shape availability, modifications to wild shape forms) are pretty important and clearly have a substantial impact on the perceived (and probably actual) power level of the class.
Attempting to fix a problem caused by home-brewed rules by suggesting even more drastic home-brewed rules feels rash here. In this case, I don't think the OP's suggested solutions would actually address the problems, either. Virtually every complaint here mentions Lae'zel being stronger than some other character/class; this suggests that the biggest issue is with Lae'zel rather than with druids.
