4.) Stats, gems, enchants and reforging
5.) Diminishing returns
6.) Dueling (work in progress)
My name is Pyrolysis and I've noticed that there are a lot of questions regarding fire PvP. So instead of posting tips in all the spread out threads, I figured it'd be a good idea to just make a fire PvP guide.
To give you an idea of my experience:
I've been playing a fire mage since Wrath of the Lich King. Since then I've played loads of arena, battlegrounds, did a lot of duels, played above 2.2k rating in 3s, and nearly at 2.4k rating in 2s (used to be rank 4# on Cyclone in season 11), and spend hours and hours searching for guides and tips on the internet to improve my gameplay.
There isn't really a cookie cutter fire build, because there are serveral talents which suit one occasion better then another (more on this later).
I'd advice to take this build as a starting point:
Based on your personal playstyle, arena/battleground setups or just for fun, you could swap around some talent points. Don't just copy another guys spec, but try to find the one that suits you best.
Here is a list of (in my opinion) optional talents:
Master of Elements: You could spec into this talent if you feel like you are running low on mana. Keep in mind that running low on mana could also mean that there's something wrong with your playstyle! If you're spamming spell steal a lot, or are in molten armor/frost armor for to long, you will run out of mana. If you want to spend talent points into mana perseverance, I'd advice to pick up Improved Scorch before you think of picking up Master of Elements.
Fire Power: You could spec into this talent if you want the extra (1,2 or 3%) damage. The explosion on your flame orb is not a good reason to take this talent in my opinion.
Improved Scorch: Since scorch will be one of your main spells, taking this talent, especially if you've got mana issues, will be a good choice.
Molten Fury: This talent is very good for scoring kills on targets with low health. The 12% extra damage can really make a difference in some games! Keep in mind though that the damage of combustion gets calculated when it's released, and if your target is above 35% health when you use combustion, it will not benefit from this talent (not even when the target drops below 35% health).
Netherwind Presence: This talent is pretty straight forward. If you need that extra bit of haste, and can't get it through gear without sacrificing to much stats, pick up this talent.
Improved Flamestrike: It's the best ability to reveal stealthed opponents, and you can keep others in combat around pillars without using Blast Wave. But it has lower or next to no value against opponents without stealth capabilities, and it breaks Crowd Control such as Polymorph, Gouge and Blind if the target is located on top of the Flame Strike location (8s).
To make it a little bit more easy, I made some example builds.
Living Bomb: Living Bomb contributes to combustion so this is a must have.
Pyroblast: Pyroblast also contributes to combustion (pyro DoT and ignite) and is a must have.
Mage Armor: Since you'll be in mage armor most of the time this is a good choice.
Fireball: A good alternative because it will give your fireball a 100% crit chance aswell (IF at 23,34%).
Polymorph: This glyph allows you to control your enemy's with a lot more ease, and is a must have.
Evocation: The only self heal (outside of cauterize) for a fire mage.
Frost armor: Good in general and especially for arena when you're facing double melee teams.
Dragon's Breath: Good for interrupting or ccing multiple targets, but keep in mind that if you choose to pick up this glyph, it will DR with it self if you use it on the same target the second it comes of cooldown. Read the chapter diminishing returns for more information about how this actually works.
Arcane Brilliance: Although minor glyphs wont make or break your games, I'd advice to pick this one up since it'll benefit you the most in a PvP environment.
Slow Fall: No more reagents needed, a very solid choice.
Conjuring: In some arena matches you might have to make extra mana gems, and this will help you out with that.
