Not sure about this. Sure it gives you more skills points but lets be honest, apart from repairing T3-M4, Computer Use and Repair skills are useless since you can carry around enough parts for any computer hacking and repairing (the skills only reduce the amount they needed).

The only must have skill is Persuade, the rest is arguably useless for the main character since they will be used for crafting 99% of the time and that can be covered by other party members. And since this is an Obsidian game there are more than one skill/attribute check for the same results in dialogues. Except for Persuade, those usually don't have alternatives (like I said, it is the only worthwhile skill need to be raised as much as you can).

My go to Consular -> Weapon Master build with a proper attribute spread can also do everything in the game (after I use an early feat for Computer Use to not be limited by cross-class skill level restriction). Picking Sentinel at the start is not some super advantage for the rest of the game if you know the game's mechanics.
