Invoker's power

[Niano]

Ok, i know someone was talking about invokers earlier, and i was too lazy to look for it. We were discussing how invokers were so weak. Mabey, instead of giving them new spells and such, though this does not effect their battles with heretics, perhaps certain spells could throw and enemy backwards, making them out of range to harm the invoker, but the invoker can still toss spells at them. Like, "Your fork lightning hurls **** backwards!"
and make some lag, like 1 or 2 rounds before they can recover and make it back to the invoker and begin to damage.
