A Hocklyn's tactical FTL isn't what you're thinking, methinks. Unlike other peoples', a Hocklyn's FTL drive generates heat by the length of time in hyperspace. Microjumps within a system produce very little heat, because it's not across quite so vast distances. 

Cirruses can go and take out hyperspace jammers before the enemy even knows I'm there. Then I can wait for the Protheans to engage and force the FPA commit to the engagement, and I can hop in wherever most opportune. I appear to be outnumbered by everyone so far, so.
