The benefits Meteor Bomb gives at 16 compared to Giant Scorcher are few and far between. Giant Scorcher is just plain better, and in some intances, I believe Cauterize Wounds at 13 compared to Resilient Flame is the correct pick as well. Of course the value goes up with the amount of high health heroes the opposing teams have, also consider how close your engagements will be.

The benefit of this build is you can lean on either your ranged damage or your melee damage to compensate if the enemy team is shutting you down in one of those outlets. Pure Meteor/Pure Sulfuras builds cannot do this and that's why I use Hybrid Rag almost every match, depending on team comps of course.

Stack as fast as you can, you meteors will be doing excellent damage and with the late game, Empower Sulfuras will be hitting like a truck as well.

Best of luck, try it out!

You will not be disappointed.
