Hi,
Everyone knows how assist units are essential to combat (especially since Brood War w/ assist modules). These units destined to support troops can cost rather alot of resources in tech and Research orders. But they are powerful enough to turn the tide of a battle with a single card without having to be front-line!
What's your favourite assist unit(s)? Which are worth their price and which are not? Can there be some very good but too expansive to reach?
But they seem to require more effort to get on my part, Queens just arrive on their own mostly (as the Queen's nest will eventually be built anyway, if only for being able to build more units).
