So I've been trolling around, trying to find a Paladin casting efficiency chart so I can figure out the best spell order, much like my Warlock. And I was kinda surprised to not find one, so I decided to write up one. Anyway, you get to benefit from a warlock-come-paladin
Paladin Casting Efficiency chart:
Basically this is the list of paladin spells sorted by the amount of dps they do, which is calculated by (max tooltip damage) / (casting time+recovery time). This chart assumes that DoTs last their full duration, you're only fighting one mob, and enough crits that the average damage of your spells = max tooltip damage. All numbers are from Ad3 figures, 680 str, 340 int, 100 spell/ca mod.
Basically this chart tells you whats the best ability to cast at any given time. It does not tell you which ability does the most overall damage, or help you get an absolute dps figure...its only good for comparing abilities in a relative sense.
6755 - Consecrate
2000 - Holy Strike
1973 - Lance (assumes non-horseback)
1219 - Break Will (assumes non-undead)
1123 - Doom Rays
1099 - Conviction
962 - Smite Evil
980 - Swift Attack(8pt)
727 - Refusal
683 - Cleave Faith
669 - Faith Strike
645 - Penitent Kick
583 - Castigate (assumes effect not removed)
531 - Legionaire's Smite(4pt)
511 - Judgement
495 - Circular Smite(m2)
471 - Heroic Dash
429 - Verdict
304 - Marr's Glorious Blade (Frog racial)
254 - Hammer Ground(4pt)
Paladin Recast efficiency chart:
The next chart is one that will give you a clue as to how big a % of dps your spells should be, given an infinite duration fight. This includes an analysis of recast timer, and helps you decide which spells are worthwhile upgrading first. For example: Faith Strike has a mediocre casting efficiency, but its quick recast means that you'll probably get more total damage out of it in longer fights that a higher cast efficiency, slow recast spell like Conviction.
123 - Consecrate
79 - Cleave Faith
74 - Faith Strike
71 - Penitent Kick
48 - Lance (assumes non-horrseback)
45 - Break Will (assumes non-undead)
40 - Conviction
37 - Holy Strike
36 - Swift Attack(8pt)
32 - Verdict
28 - Judgement
26 - Heroic Dash
19 - Legionaire's Smite(4pt)
18 - Circular Smite(m2)
18 - Smite Evil
14 - Refusal
10 - Doom Rays
5 - Castigate (assumes effect not removed)
5 - Hammer Ground(4pt)
3 - Marr's Glorious Blade (Frog racial)
Your actual dps is going to be a blend of the two charts, depending upon the duration of the fight. If its a quick 20second fight than your the optimal dps will probably match the first chart. If its a longer, 10 minute fight than the optimal dps will probably match the second chart.
If you want to find charts for AEs, simply multiply any given ability times the number of mobs in the encounter, if the ability can hit multiple targets. Otherwise leave it the same.
Another thing to note is that these efficiency charts don't include an analysis of autoattack damage. So if you time your abilities between autoattack swings, probably the longer casting abilities will drop in efficiency.
