This theory crafting made me change my gearing strategy completely.
Pasting from

Spell Effectiveness Reason
Flame Shock ~33% Damage over time portion cannot crit
Lava Burst 0% 100% crit chance when hitting a target with Flame Shock DoT present
Lightning Bolt 110% Extra 10% is from the 20% chance to proc a 50% bolt via Overload
Haste Rating
Spell Effectiveness Reason
Flame Shock 75% Instant spell, so requires GCD reduction to improve "cast time"
Lava Burst 75% 1.5 second cast time effectively makes it the same as a instant spell with respect to haste scaling.
Lightning Bolt 100%
Spellpower
Spell Effectiveness Reason
Flame Shock 189% (251% with glyph) Direct & over time spells calculate bonus damage proportionality between the two parts of the spell, but this is not adjusted by talents/glyphs
Lava Burst 240% (270% with glyph) Adding an extra 10% sp gives the 30% gain due to how the crit multipliers work.
Lightning Bolt 182% (189% with glyph)
Quite obvious scale with gemming will be spellpower (10), haste (5), crit (2) per point. Considering the gems amounts its even more (spp gem 19, haste and crit gems 16)
Of course considering hit capped for bosses (getting hit capped for thrash is more than easy).
