I am a newbie and I have 3 questions regarding the swordmage starter rotation that you wrote:
For Step 3: Lightning Orb, 1 Lambent Bolt, Lightning Orb follow up
1) After I use Lightning Orb follow up with Lambent Bolt, I can’t use Lightning Orb soon again, I need to wait 10 seconds for the first Lightning Orb to cool down.. This cause delay in my attack

do I wait for the cooldown, or can I just jump to the next step, fire-> angelfire-> lambent bolt etc?
2) How do I reduce the cooldown time of Lightning Orb?
3) What about special skills like Nimbus Reign? Where can I put Nimbus Reign into my rotation?
