All WOW healers have a more interesting DPS rotation than FF but it's only really relevant at the highest level of content as in high key levels(15 and higher) or mythic raiding.

Helping dps is appreciated but considering in WOW the damage can be extremely high...Healers heal first and foremost and damage when you can or want. Near all content in WOW isn't tuned for healer damage addition except the last few bosses in a mythic raid where that extra 1-2 percent can be bought by healer dps.

Or a high enough level key where you build your talent trees with damage in mind but without sacrificing too much of your defensive, ST and AOE healing.
