cast spells after cooldown

Freezing Wind (Summon Heat preferred) > Flame Fusion > Nukes (Big Magma Eruption/Hell Flame of Wrath/Fiery Roller/Flame Spray/Glacial Shard/Cyclone Strike) > Soul Freeze/Frost > Ice Harpoon > Flame Harpoon > Refracting shard.

Never cast anything with more than 2sec casttime without castspeed Buff up and try to keep Freezing Wind + Flame Fusion on cd at all times as well as Flame Cage on the target. Personally I recast Flame cage with every Flame Fusion out of convenience. Try to not use Refracting shard without the following chain skill.

Once you mastered that you could try to use an Orb Autoattack after every Freezing Wind. Not mandatory but helpful if you want to squeeze out that last % of dps.

As far as I know there are no orbs with attack speed right now ,so I dont think its worth to auto attack,and I also doubt that ppl will use hybrid form for that (except if they only have hybrid or physical forms )which is still inferior to cast ones

You still can weave easily without, and even more when you have wow/sod.

Imo AA are still a dps gain. Not a huge one considering AA alone, you're right. But don't forget about Arcane Combustion
And AA were never depending on Atkspeedfuses, they just made it easier.

or a chanter with atk/cast-speed skill
