- Consolidate all the dialogue skills into one "speech" skill. This better reflects the value of the dialogue skills a the moment. - The dialogue minigame makes sense for multiplayer (between players) but should not be part of the single player game. Instead there should be a fixed skill check (e.g. need 2 in speech to pass). This would create incentive to invest in the dialogue skill(s)). - There need to be many more uses for the speech skill(s) to make it worthwile. It should be possible to avoid fights and/or find alternate solutions to problems by having speech. The game is mostly hack & slay at the moment, which I find to be a pity. Some more choices and consequences would be nice as well.
Totally agree on your first point, unless Larian adds in a lot more situations where these individual abilities are actually useful (your third point). Currently, it seems like they've broken the speech abilities into three just to make the "Social" abilities as numerous as the other three categories (Warrior/Wizard/Survivor), which is completely arbitrary unless the gameplay supports it.
And agree with your second point as well - I think your suggested "fixed skill check" system is how the single-player game worked in alpha?
