I just recorded a couple quick examples of this hybrid archon/cm freeze vs. reflect dmg elites in MP1 to show the effectiveness. Obviously since there are only 1-3 mobs the cooldowns don't refresh as fast as vs. a large pack, but it does the job while getting Archon back up.
Group 1 vs: Reflect Damage / Vortex / Mortar / Frozen -
Group 2 vs: Reflect Damage / Electrified / Extra Health / Knockback - http://www.youtube.com/watch?v=HCZzNZkh9P0&feature=youtu.be
Note how fast the Archon cooldown refreshes in the 2nd video and it's only vs. 3 mobs. Get a large pack of mobs and CM procs for a super quick Archon refresh.
i'm really trying to understand why you keep insisting this is efficient build.
1st video shows taking down a pack in 20 secs
2nd video shows taking down a pack in 28 secs.
and both videos are sped up i think.
This cant be considered efficient...
Reason why we moved away from cm to archon is because there's an inherent windup time to cm. So anytime you're doing your cm windup means you're not being efficient in your run.
I think you should work on maintaining archon as much as possible instead of relying on cm to bring it back online faster.
shelendil does bring up a good point where this could be superior build in group play, where sustained-archon is at its weakest form.
