So it looks like both the Queen and Chrono Boost come up every 25 seconds and each last 20 seconds, so unless your using them on multiple targets, you need to be checking back on these things every 25 seconds, which is really hard for me to juggle with everything else going on constantly.
Is there a faster way to automatically target the nexus/hive? It's pretty easy for me to queue up gathering units, because I can just hit 1 and then E, and I don't have to move my screen back to my base or use the mouse. It just seems silly to me that the mouse needs to be used for this task because the mouse is so much slower.
Also what is the prescribed role of the Queen/Chrono Boost? Do you always want 1 queen per hive and blasting them every 25 seconds, right? And is Chrono Boost usually used on the nexus itself except when you need to rush out some troops?
