zsader might be fun and have benefits - but the unfortunate truth is that, it simply will never be as good or better than zmonk or zbar which is what I DON'T like.
Well, don't say "never" because we can always hope, right? It would be nice if all classes had a solid support option. Hats off to Blizz for all the 2.6.1 buffs and how these changes will bring more variety in power level. But, support options still need serious attention. 'Saders just naturally have a support feel to them -- you got the big shield, charging into the fray on a steed. It really wouldn't take much effort to make them viable support toons if that healing shield was buffed and those regen circles were buffed too. And probably a buff to a law for flat damage reduction.
I tried a zDps Crusader build that caught my eye awhile ago last season and it was totally viable: you're healing via blocking, plus you've got the big regen circles under everyone all the time. Then, if I recall it's Roland based so you're pulling things in with Sweep Attack. Finally, everyone's resistances are pretty high because you're activating long arm of the law frequently.
