Every point, up to 3, reduces that by 0.5 seconds. So, you can get down to 7.5s, 7s, or 6.5s.And also Fire Blast can be a reasonable addition, and if you are in a highly mobile fight, maybe Scorch becomes your main spam spell.Elemental Precision 3/3 is a no-brainer; if you don't take it, you have no brain. We like 5/5 Improved Frost Bolt so that when we need it, we do more DPS or we can cast it that much faster (Strider Kiting).That leaves 2 filler points which you could slot into Improved Frost Nova or Permafrost. Both are equally good/bad, IMO, so what you like.A fully Improved Fireball takes 3 seconds to cast. So, unless you are going to stop DPS to wait to Fire Blast, Improved Fire Blast is a waste. Fire Blast does a little more DPS, but waiting even 0.5 seconds to cast it nullifies that benefit. WOW GOLD players will likely wait for 3 Fireballs to use it, which means Improving it is a waste.In that case, if you did spam Scorches, you are hurting your DPS pretty significantly, and a single point in Fire Blast could be useful to allow you to Fire Blast after every fifth Scorch.It is a fact that the Improved Scorch debuff lasts a good long time, 30 seconds to be exact. You want to get off a Scorch before it fades, and you are not an AI, so you probably have 27-28 seconds to play with. So you can probably get off 8 Fireballs safely, and maybe a couple of Fire Blasts.
