Agreed, need to cast 3 times

3 GCD > proc and other 12-15s to make dot worth its more than 20s of the fight and 3000 per ticks is very low. its not 3000p/s but its 3000/3s ? very low dmg.
and yes Fire without dot dmg is same damage as ice. : (

This is my thought on Fire and Ice.

Burn will eventually cost 1 Recuperate after 12s which is very long. Mana regen also ticks at 500/3s so thats 2000 mana recovered.
Two Burns will cost 2 Recuperates in total after at least 30s (SF > 3 Flares + Burn Duration > SF + Burn duration) while 5000 mana was recovered, which is exactly the cost of two Recuperates.
It can help shorten the fight and lessen stalling power, but has absolutely no use against team with group Regen, extra self heal, and especially against WHM.
In the best scenario, burning the whole team would be 120K dmg in at least 30s and cost 10 Recuperates.
It is important to note that Burn can cancel NIN stealth and stop them from using Assassination and can kill people through Guard, but that is very very unlikely unless you stack it with multiple DoTs from your team.

Deep Freeze, on the other hand, will prevent 2 (or 3) Recuperates from being used during 3s deep freeze, and has a high chance to pop 'Purify' which is invaluable in team fight and disengagement pretty early on in the fight.
Two Deep Freezes will prevent 4 Recuperates which is 60K HP and very likely to pop Purify as well. This helps shorten the fight even more so than Burn ever could as it can prevent up to 60K healing and pop a purify.
In the best scenario, freezing the whole team can prevent up to 20 Recuperates, which are 300K healing, on top of popping 5 'Purify' in just 6s (SF > 3 Freezes > SF), stop dmg coming to your team, prevent the opposing team from using guard, and stop them from escaping.

Freeze really does more than Fire in only 1/5 of the time.
