it is intended to be one of the bottlenecks for optimizing, but what is strange is that it does not scale at all with difficulty. You get exactly 4 of them doing:
- level 4 CP with 4 directives
- 10 floors of summit heroic +4 directives
- 10 floors of legendary +4 directives.
How does this make any sense? One takes 10 minutes the other over an hour...
