I think that it is not difficult to make a 5-10 sec delay that would work properly after boot.

Netwatch shows wrong status (down) after a reboot is necessary to make a 5s delay after starting the system and this option does not exist.This http://forum.mikrotik.com/viewtopic.php?f=9&t=57770 leads to an infinite reboot 1s after the start although the the host is active.
