PLEASE stop telling summoners to use Ifrit!!!

Just a few notes;
FFXIV APP parser places an average value to your DoTs. This is because the true value does not show up in any text logs, which is why it doesn't track the extensions nor shadow flare damage.
E.G. Each Bio tick is valued as 89 damage for FFXIV APP regardless if your actual DoT tick damage is higher.
Your DoTs can also have critical damage ticks, which will not be recorded in the parser.

Contagion adds 15 secs to any active Bio, Bio II, Miasma, or Miasma II, [and Thunder]. Each tick for damage for any DoT is 3 seconds, though sometimes you'll occasionally lose one tick. So essentially you're adding 5 extra damage ticks per active DoT.
E.G. Extending Bio with Contagion is equivalent to shooting out 2.5 Ruins, and not taking into consideration any additional buffs/debuffs. (Bio is 40 potency per tick, Ruin is 80 potency per shot).

Egi Garuda's basic attack 'Wind Blade' is 100 potency, Egi Ifrit's basic attack 'Burning Strike' is 120 potency. Even though Ifrit has a hidden extra second totaling its basic attack to roughly 4 seconds, it'll still deal a tad bit more damage to Garuda's 4 seconds 'Wind Blade'. Again, this is not taking any external buffs/debuffs into account.
