Negative synergies

While browsing the WotLK alpha wiki I spotted these two talents:

Burnout - Increases your spell critical damage bonus with all Fire spells by 5/10/15/20/25% but every time you critical with a Fire spell you lose an additional ?[internal entry blank]% of your total mana.

Hot Streak - Any time you cause 3 spell criticals in a row you have a 33%/66%/100% chance the next spell will gain 100% increased chance to score a critical hit.

So, if you crit you'll burn a percentage of your mana, and if you happen to chaincrit you crit some more. Hopefully Hot Streak has an internal cooldown or a counter that resets whenever it activates. But even then the "synergy" between these two talents can be devastating to the sustained damage of fire mages. Assuming you don't overaggro first, that is.
