I like my Excalibur as well. I was not saying anything against that so I hope you didn't take it that way, I simply wished to correct that info because it was likely lowering your damage quite a bit seeing as you were probably losing more than 50% of your chances for the additional effect to proc.

In either case I agree enspells should be fixed, they should be the lowest priority of additional effects, or what they really should do is allow enspells to stack with other additional effects overall. The fact enspells & other effects do not stack is another reason why /DNC falls far behind /NIN, seeing as you have to lower DPS by giving up Excalibur procs or Enspells, so you can get samba effects. Also it lowers the power of Excalibur over all thanks to the enspells being given up.
