Offensive Priest Spells

A quick question for people, do you think priests have enough of a range of offensive spells?

As I see it we have one DoT and three offensive spells:

1) Mind Blast - a good spell but on an 8 sec CD for holy priests and producing a lot of threat

2) Smite - 2 sec cast time

3) Holy Fire - 3.5 sec cast time and not enough damage to justify itself.

Sure we have some others:

1) Holy Nova - 'nuff said

2) Mind Flay - again very nice but channelled is a pain when you are being hit

3) Another DoT

Does anyone else think it would be nice to have a wider range of offensive spells? And does anyone have any ideas about what those spells might be?
