I’m pretty similar to you.
I ink a pretty decent path on my way to the centre area, do some work there, make some sorties deep into enemy territory and on my inevitable (most of the time) respawn I take care of what my team has missed back on the way to the centre/bad guy side.
Works pretty well for me!
I’ve seen the opposite too, though, people inking every tiny little blank space.
You’re absolutely right in that it’s more advantageous to be cover/recover more of the enemies ink than spend entirely too long covering the tiny little bits in corners.
It’s all fun though. (I save my salt for Ranked, haha).
