Treants and starfall ar both really good spells. I use them as much as i can in BG's, because thats the only way i can survive 1v1(we all know we suck in pvp atm).
But, the CDs are way to long to be usable, or "spammable", and they are the only spells we can truly own someone. For example, rogues imo, dont have any cds anymore. Vanish, sprint, cloak of shadows got like 1-2 min cd, wich they use all the time.
Starfall and treants having 3 min, wich i cant use as much as rouges or any other char. And i cant really say any class having such cd anymore on their talents, well shamans having their wolves on 3 min cd, but they can do much much more than Treants.
So my suggestion to improve the pvp for balance druids is to lower cd on Treants and Starfall by the maximum of 1 minute. It would really be helpful, and i hope blizz will do something about these spells. Anyone agree?
