It's so bad. Only saving grace is the the total enemy count is usually manageable but I missed being able to just call for a focus swap and watch them melt like you do in WoW.

These days I just play monster hunter. No comms needed but you have to learn a weapon up front.

Me and my friends started comming recently on some harder monsters in Monster Hunter but it's completely unnecessary as you said. Stuff like, "mount finisher" "setting trap", all stuff that you could visually observe. The main benefit has been I'm much more cognizant of my teammates than I ever was in the past. Now I actually look at what my teammates are doing instead of just tunneling on myself.
