Network Impact of the Gameplay Ability System GAS

Hi,

I am currently trying to evaluate whether I should switch my own skill system for the Unreal Gameplay Ability System. Since I am working on a mobile game, I try to make the network calls as lightweight as possible, so I am wondering how much traffic is introduced when switching to GAS.

In my own system, the traffic is limited to 2 reliable calls and a few replicated variables: Starting the ability, commiting the ability and replicating the variables health (to all) and mana (to owner).

How much traffic would I have to expect from the GAS for this usecase? Can I control the GAS replication in such fine detail by myself or do I have to stick with the 4 different modes that are mentioned in the docs? [1]

Thanks in advance.
