How would you make RDM more complex?

[Miyoyo]

I enjoy Red Mage as the simplest dps and can definitely see why others want to keep it that way, personally however its missing jussssst a little bit of depth for me to find it enjoyable.
So with that being said...
I'd like to see two dots, 40 potency or so, 30s duration (in line with bards) and gives 1 black/white mana every tick.

Then at a higher level, give them a scourge like ability, spread the dots but with half the duration, so you'd put the dots on a single target, then spread it to 5 or 6 targets with a 15s duration.

This would add a tiny bit of complexity to single target gameplay, having to keep up two very simple 30s dot but also do a lot for red mages rather poor aoe game.
On large pulls you'd essentially be gaining anywhere between 6 and 10 white/black mana every 3 seconds which gives you a lot more mana to spend using Moulinet as opposed to almost entirely scatter.

Although i don't imagine necessary they might cap the mana generation at 10.
