Temp Boosts and AoEs

I'm just doing some of the maths on a few of my toons to work out their damage per animation and damage per animation for the best attack chains for them.

Does anyone know a good way of working out the damage of an AoE. I'm assuming 5 council all bunched up, 1 in the middle, each one 5ft away from the middle one, 10 feet away from each other.

And what is a good way of working out buffs like destiny, Aim, Build up, etc and how much boost they give in general in a long fight, assuming they are hit every time they come up.

It's hard to average the damage of an AoE in any meaningful way unless all you plan to do is to run the same mission at the same reputation, as even given the same enemy group at the same level range, they will be positioned differently on different maps, as well as architecture hindering or helping your effort (think council cave map as opposed to outdoor portal corp map, for example). I'd say your best bet is to track what you yourself usually do and how many mobs do you hit on average with any particular AoE, and derive numbers that work for you from that; although that sounds like an awful lot of work. Knowing AoEs are generally efficient as soon as you hit 3 targets, I tend to just use mine when I know I'll hit at least that and not sweat the exact damage I'm doing.

For static buffs all you need to do is multiply the duration by its uptime, and then deduce the animation time from your total damage. It won't be perfectly accurate as there's, on one hand, chances you might optimize the build up period better with high-damaging moves and travel time from mob to mob essentially cutting into recharge, and on the other hand, the possibility you might waste it due to other concerns such as survivability or the current enemy group being defeated while your buff is still in the middle of its run, but it's a good enough approximation IMHO.

Destiny is trickier as the buff potency changes over time. Some people like to average it out. Some people like to take the lowest value. Some people like to treat it as an emergency click. Once again I would say the math you'd want to use would depend on your own playstyle.
