Pure Fire druid questions

I started this druid to try something new, and maybe be good in cow games I lack experience in druids so i need some questions answered

I was thinking 20 firestorm 20 fissure 20 molten boulder 20 volcano

1) Should i max armagedon as well?

2) If i max grizzly (as a fifth maxed skill) , will i be able to handle fire immunes in hell? (count in the mercenary too). I also know that volcane and molten boulder are 1/2 fire 1/2 physical

3) I want to use an act 5 mercenary with lawbringer eth legend sword. is this a good idea? it would trigger decrepify (level 14 i think), so that would help against Fire immune too. want to be different thats all

4) will this be able to kill fast in cow games ? and lets say player setting 3-4



Thanks a lot |||1.) Probably not. There's not much good to say about Armageddon.

2.) They will die, but not fast.

3.) Act2 merc with Reaper's Toll would be better.

4.) IMO, fast cows = Javazon or Blizz sorc, Fire druid would probably be medium.

I've done a pure Fire Druid. It is fun but really slow against fire immunes. Check out the Fire Huntermentalist guide. A lot of people speak very highly of it.|||thanks a lot
