Forgot to mention that I hate Bane has such a low range. People that don't understand summoner need to learn / realize that if there is an add fight - we can do really good DPS on it, you just need to bring the add to the boss / main target so we can bane spread our dots on to it, and we'll be wrecking it pretty quickly.

As far as contagion - it's to add 15~ seconds to all your dots, making them do more damage with less casts. It doesn't re-calculate the damage. what I mean is this: ( Using rough numbers )
Normal DoT ( Bio ) is ticking for 40 damage - lasts 15 seconds. When Garuda uses contagion, it's doing 40 damage a tick, for 30 seconds instead.

Also, if you use that in junction with Raging Strikes up, they are also doing extra damage, for a longer period of time.

We are starting to work on titan this evening / the next time we are together so I'll let you know how that goes, but so far I've been able to keep track of stuff and still throw in Ruins.
