newbie question - dream/storm combo?

[Ganymed]

Hello, I am a newbie here.

well - so I have to start all over again to use the new "dream" mastery....
I am only wondering about a good combination.
In original TQ I made two chars:

my first one was not satisfying (male nature/hunter) and I finally failed in the beginning of Legendary Act 3 due to permanent huge damage taken/too many deaths, too less damage dealt even with not that bad equipment (thorny maul, all purple). I gave up with level 55.
my second was female earth/spirit and that worked far better. the pets were good, triple shot with the staff is a fine thing and I finally managed to beat Legendary, char. is now lev. 56.

For the add-on I would really like to use masteries I did not try until now. due to the failure with my first char I did not want to make a melee char again, but a caster (again).
I considered a storm/dream combination.

before I start (I do not even have the add-on until now, to be honest, but was reading everything about the new features), I want to ask you "experts" if this is a good idea for a complete replay (I dont wanna fail again and be forced to give up at level 50++ due to a bad combination)

thanks for help

There is no "BAD" combo and note that purples can be worse than greens.
Resist are more important than DPS.

One note +%lighting does not help electric burn damage, but you can get huge debuff with these two masteries via squall and ToW.
And Wisp eye of the storm boosts all elemental damage.

Over all i think it be fairly good.
