But again, the people that would abuse macros are the same ones dissuaded by actually having to go through some other set up process.
If you include it directly into the game as a "press this key, spam this text" option, you will 100% encourage their abuse.
While they exist, the arbitrary difficulty in using them curtails the abuse.
You see what I mean? It's a catch-22. By adding them you ensure their over-use. Even though you can do it now, since it's not "part of the game" it won't be heavily abused.
