well Havoc has it good sides aswell, like:
- Shockstrike can have 32 meter range if Bombardment is fully feated making it pretty usefull in certain situations

- Overloaded Shockblast is very powerful when fully feated, beats Inferno of Amher easily
- Demonic Wrack, decreases targets electrical invulnerability by 5%..nice when playing with a few ToS who also uses their debuffs

- Thunderclap, strong channeling spell with chance of knocking back your target(s)
- improvements to Storm Chains are nice. long root with nice pulsing damage
i played my demo first with conflag build but around lvl70 changed to havoc and really enjoyed playing with it

Now i'm back to conflag because of raids. I've tried several builds with havoc and hybrid and it was really hard to choose which one i take. I ended up with conflag because it has greater dps.
but i recommend that you try both trees
