It has 2 highslots, meaning you can mount both a probe launcher and a cloak.
It has an abundance of mid and low slots, giving a large variety of configurations (cargo, stabilisers, tank are the most common options)
It also is not as destructive on wormholes as the largest hauler you can take into a c2-4 wormhole.
A C2 wormhole can take 2,000,000,000 kg.
An orca is 250,000,000 kg; 4 round trips will break one. Wormhole residents use Orcas and Battleships to deliberately break one.
An Iteron Mark V is 11,750,000 kg; 85 round trips to break one. While each Iteron Mark V holds 1/2 of what an Orca can, the total volume that can be hauled through any given wormhole is much much bigger. I have known wormhole residents to break a wormhole with convoys of Iteron Mark V's when they get a good connection.
In a wormhole, Iteron Mark V's also have the solo survivability of a solo Orca. That is blessed all. I have been tackled in a wormhole with an Orca, and been tackled in my Iteron Mark V. The only difference is how long it took me to 'pop'. I will admit that my orca did not have 2 warp core stabilisers, an expensive mistake. The extra stabilisers may not have saved me anyway.
There are two things that I have mixed feelings about:
- Large Haulers to get only 1 high slot. (down 1). For us the Iteron Mark V has been the pinnacle of wormhole hauling. Easy on the wormholes, large storage, a cloak and a probe if you get stuck. It has been the only ship to use. The loss of that highslot means we have less fallback options; and probably means a dedicated scanning frigate per interim system (for us - generally 1). We will have 'interesting choices' that have to be made; but for us; this is a hard nerf.
- The Bestower takes the crown as the largest hauler (39201m3 t1 rigs/t2 expanders/max skill) from the Iteron Mark V (38433m3 similar configuration). While the manufacturer in me rejoices; the pilot weeps. I trained Gallente Industrial 5 to have the maximum size T1 hauler. The difference is marginal (2%), but I fear I am still coming down with the beginnings of bitter vet syndrome.
