Double sentinel might be the worst comp form. Deadass idk why EDG are using it.
What is the main point of sentinel on attack? 1.) Lurk 2.) watch flank. It's really just redundant espically when ure losing either info or util to exec the site. It's not even better on defense. You have less util to reclear space, less info of where the enemies are meaning you can only set up on site. But teams are so good at taking sites now, playing retake is normally the call you have to do, making senti's kinda useless.
Double initiator should be the meta.Provides a lot more info + site execute potential.
Double Duelist. Most double duelist comps have Yoru+another duelist. This provides info+ great site exec abilities
Double smokles. Although not as good in this meta, smokes always provide value, especially if your team plays a slow default heavy style, or if you're using viper + a secondary smoker.
Double sentinel is just redundant.
