Druid treant form

Hello guys, I want to type here some of my opinions and ideas/wishes what could be done with druid treant form…
I am talking about treant form not about main ability that transforms u to a treant for 30 seconds.
Okay so first of all, I dont know why but blizzard left it untouched few expansions ago… Why doesnt it offer the same bonuses like other forms? They just made it completely useless: No polymorph protection, no healing bonus…
To be honest I loved playing resto druid in treant form that I could just use whenever I wanted instead of having it only as a main 2 minute ability… And also the next thing is that it really feels like to me when Im playing resto druid like playing resto shaman without the form… So feral has cat, giardian has bear form, balance has boomy but resto has no form, just 30 second 2 minute cd ability? I just wish they added something similar like moonkin form bonus that increases your spell damage by 10%…
My final ideas and solutions to my wish about treant form:

  1. Give polymorph protection
  2. % bonus to healing
    Thats all i really wish for make resto druid feel like resto druid not like shaman without druid form… thanks blizzard
