All tutorials I’ve seen do that. But the Ability System Component is already available to add, in blueprints, once you enable the plugin. Is there any reason to bother with C++ on this?
It expected to be used in multiplayer so to have better latency when using c++. (even tho single player will work fine)
The main reason is that more methods/event are exposed in c++ compared to the blueprint version, as mentioned here: Your First 60 Minutes with Gameplay Ability System | Tutorial
Also note that epic staff might add more function/event on each new iteration of the engine so some article might say x thing is not exposed in bp but is actually present in a future engine version.
Another reason i could thing of is console because playstation library api will probably need your project to be in C++.
