Amarr has a weird progression, it used to be very focused on lasers and then more lasers, and CCP has since shoehorned drones and missiles into various spots. At first it was mainly the t2 khanid ships getting missiles, but now there is a line of neut and drone boats in the t1 line, with some overlap with the ewar line.
the armageddon (5/5) and prophecy (4/4) both have the universal slots, and I suppose you could argue the dragoon already has universal slots as it has 3 of each hardpoints so you could fit launchers or guns and then that leaves the 3 other slots for neuts/nos.
Which still leaves the arbitrator in a weird place. the 2/2 layout with no bonuses to weapons or neuts is just kinda wasted, It's highslots are just going to be gimped whatever you do. It's a very similar ship to the vexor, yet I feel like I almost never see arbitrators and vexors are pretty much everywhere. Vexor has more EHP and fitting room which matters for pvp, but for alpha level pve the differences aren't too big.
split weapons have long been considered a bad thing, it's why CCP rebalanced the typhoon (guns, launchers, and drones), the dominix (drones and guns), nightmare (guns & launchers), merlin (guns, launchers), tristan (guns & launchers), and probably a few more to focus on one weapon system. Sure they might be able to use a second, but their main bonuses and slots are to one kind.
As for the SoCT ships, We mainly have the gnosis which is a limited edition ship and the supply is CCP controlled. It's way more expensive than a t1 cruiser. Sure it has universal slots, but it also has universal bonuses and players typically fit it up to max a specific bonus of their choice. sunesis is also a thing but expensive and doesn't seem widely used.
and concord ships are way out of the reach of alpha characters.
