Yes, it has always been a gripe of mine that a starting Sammie can wipe the floor (statistically speaking) with a starting Adept.
However, I tend to see the advantages in more abstract terms. Yes, a sammie for example is a very limited character. Great if that's all you want to play. But look at some of the adept powers. One that I found a particularly interesting use for is Multi-tasking. OK, not a combat power per say, but imagine if you are say an Adept who is say a leader of some group (military, merc, standard runner team, dosent matter). Being able to read the situation, issue orders, send return fire, etc all at the same time can be a VERY good thing when the waste matter hits the occalating cooling device.
Another adept power, linguistics. Being dropped into a new territory and being able to get at least a rudimentary understanding of the local language, also a VERY good thing.
So I guess the point is, that while in raw power the adept is at a disadvanage early on, creative use of adept powers can go a long way if the player is smart and that to me is a real advantage.
