Ranked mode or Turf War? In Ranked nobody really inks the base, which I’m glad for…because when I use Splashdown I like to ink non-inked turf to build my special guage faster and then super jump directly into the battle field using Splashdown to splat the enemy try to kill me at jump-in. Works very well most of the time! Also, the higher you do a Splashdown the larger the radius seems to be for those to take damage in.
If it’s Turf War a lot of the squids will try to take an early domination of center field but there’s really no excuse for not inking your base straight away. Most battles get determined in the last 30 seconds of the match anyway.
