MW Math #3: Comparison of AOE (Area of Effect) Skills v2

This is a revamp of another post found at this link. Basically I'm just trying to find the best AOE skill by damage.

1) Firstly, list all heroes with AOE skills and list skill stats (as base, since power goes up at similar rates, this should be accurate, with the exception of William, so I'll use his level 3 skill that is about even instead.)*

Galahad: 40%-93 damage
Sarky: 40%-220 damage
Merlin: 30%-180 damage
William: 50%-164 damage
Lancelot: 40%-68 damage
Einar: 40%-85 damage
Edward: 40%-52 damage
Gawain: 40%-57 damage
Mary Read: 40%-60 damage
3-star musketeer: 40%-180 damage
3-star archer: 40%-81 damage
3-star William: 40%-123 damage
3-star Galahad: 40%-91 damage
3-star Gawain: 40%-56 damage

2) Assume a battle is 1:30 long. Heroes will proc about the percent rate out of ten seconds after their cooldown. If you don't understand this, basically it means Sarky will proc every 14 seconds (10 second cooldown + 10 - 40% seconds (one attack a second, 10-40% = 6 seconds). Then divide 1:30 by often the hero procs-so Sarky would be 1:30 (90 seconds)/16 or 90/16 = 5 procs (always round down because the battle ends before the hero can proc again).

Galahad: 10s procs, 9 procs per battle

Sarky: 16s procs, 5 procs per battle

Merlin: 12s procs, 7 procs per battle

William: 9s procs, 10 procs per battle

Lancelot: 10s procs, 9 procs per battle

Einar: 9s procs, 10 procs per battle

Edward: 12s procs, 7 procs per battle

Gawain: 10s procs, 9 procs per battle

Mary Read: 12s procs, 7 procs per battle

3-star musketeer: 10s procs, 9 procs per battle

3-star archer: 9s procs, 10 procs per battle

3-star William: 9s procs, 10 procs per battle

3-star Galahad: 10s procs, 9 procs per battle

3-star Gawain: 10s procs, 9 procs per battle

3) Multiply triggers by amount of damage to get total damage.

Galahad: 837
Sarky: 1100
Merlin: 1260
William: 1640
Lancelot: 612
Einar: 850
Edward: 364
Gawain: 513
Mary Read: 420
3-star musketeer: 1620
3-star archer: 810
3-star William: 1230
3-star Galahad: 819
3-star Gawain: 504

4) Conclusion-Well then... That's interesting...

*for heroes with skills that do damage multiple times, the total of amount of damages + damage amount (lololol)
