Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi

I wish to know if a Shaman, with an enhancement specialization, should also put some points in the Heal Tree, or in the Elemental one.

Also, is it better to fight with 1H weapons or two handed ?

Thanks a lot for your answers

In PvP - for sure, otherwise you'll receive a suicide bomber with tonz of burst damage and 0 survivability.
It's also better to use 1hander+shield vs meele opening (rogue / warrior), but the main burst you obviously deal with 2hander.
Try to find a weapon switch macro for fast switch during the combat.
