We'll be sure to pass along your ideas to Blizzard.
It seems that there are two major issues with fire in cataclysm, which are currently discussed:
1. The mana issue
2. That it's much less fun to play than fire at 80
The first point can be simply addressed by changing the manacost of Fireball or by changing MoE, as has been mentioned in previous posts. The second point is strongly related to low combat ratings at 85 entry level gear, especially crit rating. In such a world, crit based proc mechanics seem outdated anyway. A big part of why frost is by many beta players regarded as "more fun" is that it's procs are based on fixed percent, so it will feel the same on all levels of gear. The numbers will just grow.
In the following I want to make suggestions how important fire talents could be changed to drop the crit dependence of fire:
15% chance for all fire spells (direct damage that is) to leave a dot on the target doing 100% of the spells damage over 6 secs. Proc chance is low enough to prevent constant overwriting from multiple procs. Damage gained would be similar to current ignite with 37.5% (0.4*0.375=0.15) crit.
Flat X% chance to proc on any direct fire damage, similar to fingers of frost.
Master of elements:
Y% chance on any non periodic fire damage to restore Z% of maximum mana.
Additional suggestions not directly related to the issues mentioned above:
- Buff Fireblast damage to make Impact impact procc really useful on single targets
In addition to its current effect it also grants the haste buff after the use of Pyroblast!, similar to t10 setbonus. If the numbers of hot streak and pyromaniac are adjusted properly, fishing for HS procs using scorch and casting FB during haste buff would provide us with a straight forward way to incorporate scorch into our rotation in case the mana issue isn't fixed otherwise.
