I've actually played through Mass effect 2 & 3 as both soldier and Adept, while soldier made the game easier due to its mastery of any and all firearms at the get go, I found that Adept actually afforded alt more fun, in Mass Effect 3 you gain a new power, that is the Biotic charge, where you surround your body with a biotic shield and slam into a foe, every living thing around you takes massive damage, I really liked that power, of course you lose all your shield power for a moment, so it should be taken with a grain of salt.
The adept class is a lot of fun. What I like most about it is that no other game really has anything like it. It is a really cool idea that was a little rough in the first Mass Effect, but is really well polished in Mass Effect 3.
I always considered Adepts to be very powerful. Although I play mostly as a Vanguard, I always took an Adept like Liara with me on my adventures. They just lend support and massive firepower to any group. Adepts are like Mass Effect`s version of Mages.
