I completely agree with this - extra abilities may be interesting, but to be able to get more and more powerful abilities, just by playing more, would throw the balance out. The mods are already a nice touch though.
I don’t know if this was supposed to be a “place your ideas here” thread or simply a “here’s my own idea” one, but for me, the voice options need more selection. For example instead of just having “help” have “I need healing” and “I’m being attacked”. The healing line being one of the most important, in my opinion.
