I'm guessing they're starting characters (IE their stats obey the rules for creating characters without additional skill or adventure points having been spent)?
One of the issues is that TOR assumes a long-term campaign. A starting Company is built to be poor and likely to fail tasks to provide contrast with a veteran Company. That's fine with a campaign, but for a one-shot or an adventure for a Starter Set, it can get very frustrating and can feel a bit hopeless. They have to decide between being competent in combat (and spending 60% of your XP on that alone) and being pretty rubbish at skill checks or being competent at skill checks but being sidelined in combat.
In a campaign, that's fine because you gain SPs pretty quickly to rectify that (or can choose to buff combat Skills to remain relevant in combat), but in a one-shot or a taster...that can be problematic.
