DoT questions

4) Whatever buffs (and certain debuffs) are up when the dot is applied will affect the entire duration.

Let's say I use Cleric Stance, cast Aero, and switch back, will the Dot apply the damage with 'full cleric power' every tick? Same goes for Raging strikes?
If I use Bio, Miasma and Bio II, and then cast Raging Strikes to start spamming Ruin, will it be 'wasted'? Should I cast it before the Dots?
