Infiltrators

So, I’m a dark angels player. I’ve got an RTT coming up and I’m going to be trying out a list by Happy Krumpin as I have had some luck with the components myself.

What I’m stuck on is whether I need to include Infiltrators in my list anymore. I have been using them to fully screen out my back objective, mainly because of death guard, but I’m not sure if I have to worry about them AS much.

In lieu of infiltrators, I thought that I could include Heavy Intercessors because they’re especially hard to shift in Wrath of the Rock, or even just standard intercessors for sticky (I don’t have another unit with sticky in my list).

What do we think? Playing on GW terrain
