Before everyone tells me to drop my idea and do a support Monk - I get it. Monks are better. I have done support Monks many, many times. But, if everyone just did the same thing as everyone else - where's the variety? We're not all sheep are we? Anyways - I simply want to get my clanmates' gems to 65 for that one Conquest this season - so I am assuming a good support Crusader is at least capable of keeping everyone in the group alive in 75s. That's it. I just want to do 75s. So, I'd appreciate links to builds to what you guys would recommend for a recommended zdps Crusader build. And I have looked already, but there does not seem to be a consensus. Thanks.
There is no consensus because the general consensus is that support crusader is dead. It's mainly because of the CC changes: most of the crusader's abilities have cooldown, so can't be spammed, but you need to spam skills in order to get applied because of the ridiculous CC resistances in groups. This is even more so the case for the crusader as many of his skills have no effect at all if they get "resisted" by the mob (especially talking about Judgment here).
The question is: how fast is your group. If you're regularly going over 8-10 minutes, fights are more stationary and you might try using Gathering Sweep to create nicely stacked groups. For any other occasion, or in general, I suggest Condemn-Vacuum. The Steed Charge - Draw and Quarter rune is unfortunately more gimmicky than anything else because the mobs will resist a "pull" in 19 out of 20 attempts when they have max CC resistance.
Besides that, just the usual group buffs: Critical for DPS or (more likely) one of the defensive laws to buff toughness. Of course stack CDR like crazy. Regardless of whether you use Sweep or Condemn, you should definitely also stack lots of wrath regen and RCR to be able to spam those skills indefinitely and therefore proc Obsidian A LOT, which helps even more with CDR.
The exact choice of skills depends on your group's needs, composition, and speed. It's like the monk: the #1 spec that the top players use is not the best one for speed farming or GR65s, you'll have to improvise and take whatever you think complements your group best.
