What I meant was that the difference going from 15% armor and 5% dodge priest to a 45% armor and 14% dodge and 5% parry warrior is quite huge for crusaders scaling. Its over twice as good against the priest than its against the warrior. Nowdays scaling with crit and haste arent that much of a point since after proff/enchant nerfs crit/haste levels are pretty standard or vary very little, thats true.
Applying rend or using op during crusader increases its value as well as using thunder clap. On the otherhand using those during the proc means increased chance to refresh the proc while old proc is still on, making it less useful. As said its not straightforward.
Also 2h benefits more from crusader trought overpowers used during the procs. Also without maths you cannot say the increase in amount of procs is worth the same for both enchants (for example, more procs means more overslapping for crusader). Again hardly straightforward.
Yes, it's clear that crusader benefits more from hitting low armored targets, but that's irrelevant in a comparison with lifestealing, because, as I mentioned, it also scales with melee crit, minimizing the net variance. Avoidance is a complete non issue, as both enchants scale with it.
Refreshing the proc while the proc is still active is also less of an issue than you make it out to be, as unless you are taking back to back procs of each (something that would occur about once for every 250 sets of swings for crusader with BAR, less than 1 in 250 for any other weapon) as your example, you are still gaining partial benefit from the refresh, with a low chance of it even happening.
In short, you're making a lot of fuss over details that add up to minimal dps variance.
Basically, unless you're going to try to mathematically challenge something that has been common knowledge for years, arguing against it looks a little foolish. I can understand why you would choose not to waste your time with such a mathematical exercise, however, feel free.
Also, a 2h does not benefit more from overpowers during the proc, as without access to improved overpower or taste for blood at level 19, overpower is simply a second chance to take a swing that was avoided. You're simply making up for the damage that you lost from that swing. 2h loses more damage from being dodged, gains more from overpower, no net difference.
Crusader for damage, lifestealing for healing, same as ever.
If you want to challenge the research that has already been done to death on the subject, the onus is on you, not me, to provide math I'm afraid.
