Honestly, i don’t think you do.
No. I think that is a terrible way to design commanders.
One unit that can counter everything - like ravagers, are bad. Ravagers did not have those crazy OP biles back in the day, yet Abathur was still considered one of the strongest, if not the strongest commander.
The same goes for hero commanders that can solo pretty much everything - like FoM Kerrigan or Best Buddy. I think that is bad too.
They disproportionately reward you for playing 1 hero unit well. If that alone gets you excellent results, how can you then reward someone fairly who performs the same with 5 units at the same time? How about someone with 5 unit groups at the same time? The former one doesn’t need control groups, or any multitasking. Nor does he risk to loose any resources.
That seems to be inherently unfair to me.
Swanns buildings are not instantly build. Do i really have to emphasize the difference?
How does it feel to control a probe for 80% of the game, making 5 cannons and batteries a minute while your ally is microing ravens, libs and tanks as well as nova and the rest of their army, that requires as much actions in 5s as you do in 60?
Eh, I get it… the game doesn’t feel as good, if you can’t go afk mid game without noticeable losses or any significant difference in your contribution to the game.
But jokes aside - should cannons be a viable option? Sure. However they should not outperform someone making less cannons and more units that are microed well. Cause the latter one needs more effort and skill - and that should be rewarded more than building cannons.
