Class balance in the Space Wizards franchise is a funny thing.
In Space Wizards 1 Soldiers and Adepts were amazing, Vanguards and Infiltrators were pretty good, and Sentinels and Engineers were completely worthless.
In Space Wizards 2 Infiltrators and Soldiers are amazing, Sentinels and Engineers are good, adepts are okay, and vanguards are useless.
In 3 Vanguards are godlike forces of destruction, Infiltrators and Adepts are great, Sentinels, Engineers, and Soldiers are decent.
If you keep your class when transferring from 2 to 3 you get to keep your level, so it's something to take under consideration.
