I’ve been playing with the Nomads quite a bit since release so here is my take on them.
The Nomads have the potential to make the fastest frigates with fairly high hit point scores through the use of the Nomadic Frigate Engine and Armoured Powerplant. The Ummer is the pick of the bunch as a skirmisher - I like a variant armed with an Ion Cannon and EMP II and a speed of 1.02. The Mawasi can make an impressive heavy frigate in the rare instances when deploying the type is worthwhile and is equally strong in the equally marginal armoured anti-fighter role.
Crusiers are generally decent with the Hajaya being the best choice for most situations- 8 hardpoints is high for a cruiser with 17 modules and 175 metre size means it is not barn door sized like the rest of the hulls (although it’s appearance suggests otherwise!) The beam laser’s offensive advantages are modest (get some damage in early on in an exchange?) but it has high hit points compared to the standard cruiser beam and requires one less crew. The missile system will (according to the number buffs) out perform multi-warhead missiles at extreme range so missile boats are king. In theory Nomads are the race of choice for extreme range missile combat, but they don’t have overall dominace as they lack a bargain basement cruiser hull with lots of hardpoints (e.g. Fenrir or Sekhmet).
Fighers are adequate, again with only one really good option, this being the Awazem. The dogfighting laser is a great concept that should give the race an offensive edge if the stats get re-balanced. Currently the weapon is inferior to the generic fighter lasers in every practical regard.
Overall I like the Nomads as they encourage a balanced force make up - the frigates can hold their own on the front line in a way other races can’t quite match and can be used to play havoc with an opponents battle line while the missile boats lumber up and do the real damage.
