Quick Question Regarding Trinity Combat

[TLM Nuclear]

Since my wizard uses the firebird spec, Blizzard (Apocalypse rune) is my main source of damage. However, the way the bot is set now, it will cast blizzard once, and if/when the enemies run out of blizzard, it won't cast again for another 4 seconds or so. I'm not quite sure where to go to change this. Also, I wanted to set my bot so that it will cast Hydra, Blizzard, and Black Hole mainly and only cast my primary skill (Electrocute) once my Arcane Power gets below 45. I was messing around with this second part a bit and I came up with this:

// Electrocute
if (!Player.IsIncapacitated && CanCast(SNOPower.Wizard_Electrocute) &&
((Player.PrimaryResource <= 45 && !Player.WaitingForReserveEnergy) || Player.PrimaryResource <= MinEnergyReserve))
{
return new TrinityPower(SNOPower.Wizard_Electrocute, 40f, CurrentTarget.ACDGuid);
}

Essentially, I want the bot to mainly be casting the other spells and only cast Electrocute when it's below that Arcane Power threshold.

Any suggestions? I'm not experienced at this and would love some advice
