That's because it scales with Spell Damage (which is absurdly hard to find) instead of Weapon Damage (like Blockade), which scales better with high-end gear and lots of buffs.
EDIT:
I don't have fully exped EF because I always found it extremely weak:
tested it at lvl 42, 39% crit, with +66% flame DoT damage passive
Blockade of Fire (IV) ticks for 79 (118 crit) every second, 4 times.
average 377 damage over 4 seconds
Engulfing Flames (II) 72 instant, then 57 (86 crit) every 2 seconds, 5 times.
average 414 damage over 12 seconds
over Blockade's 4 seconds it would deal instant damage + 2 ticks (average 208 dmg)
So, on my level and stats:
Blockade has 94.25 dps
EF has 34.5 dps
Conclusion: EF is not even worth considering into your build... unless you REALLY REALLY want that +10% fire dmg taken.

Yes, spell power is harder to find than weapon power.
BUT:
weapon power is divided by 1.9, while spellpower isn't divided at all, so the difference between those two is not as large as it appears.
At max lvl with decent gear, EF deals 92 damage with 414 over the next 8 seconds. The DoT is affected by the +10% fire damage making it 455.4, add in searing heat (passive), and the skill deals 681.1 over 10 seconds, which is 68.11 DPS. The skill has a base cost of 280, so it has an efficiency of 2.42
Elemental blockade deals damage every .95 seconds over 3.5 seconds. Which means it deals at most 3 ticks of damage, at max lvl with decent gear each tick deals 85 damage. That means it deals 89.4 DPS, but it costs 364 so it's efficiency is only 0.70.
Which skill is better depends on what you are trying to do with it. EF is a good skill to start a fight with, as the debuff will help your other fire skills & it has a long duration. Elemental blockade is a good AoE skill, but if you tried to keep it going on a boss or something, you'd run out of magicka pretty fast.
The best guess at the formulas (they give the correct results for skills).
wpn_skill = (max_stamina or max_magicka/ 20 + wpn_dmg / 1.9) * skill_coef * rank_coef
spell_skill= (max_magicka / 20 + spell_dmg) * skill_coef * rank_coef

You, sir, should play the game more and theoretize less.
If you can count up to 4, you'd see that despite tooltips, Blockade DOES hit 4 times.
From my tests you can clearly see all those bonuses (+10% dmg, +66% damage) go to waste on REALLY weak DoT. So either that +66% passive doesn't work at all, or the base damage of EF is THAT *** WEAK.
Magicka efficiency is great and all, but it doesn't help much if you're dead - in VR you need DAMAGE and you need it FAST. Especially after nerfs to talons which makes us pyjama guys absurdly vulnerable (forcing us to use Coagulating Blood or Razor Armor.. or at least Ash Cloud to dodge some)
It still MIGHT be worth it (purely for that 10% fire dmg taken) if you ONLY use fire skills and have a free place on bars for it. But the damage of the skill is really, really bad.
