Echoing cry + skeletal brute breaks entire summoning

Echoing cry can be added to skeletal brute which leads to a few issues:
1) (exploit) - you or brute do not need to move to use the command skill again, effectively ignoring the echoing cry limitation
2) you have to move TO SUMMON brute. If brute is at top of skill gems list then it breaks the entire sequence as none of the mobs get summoned when you change locations. And you cannot resummon them unless you move and then forcefully do summoning again (change weapon or number of summons).
