with the Jem'hadar/galor/d'kora, they all stack up quite well to their fleet counter parts. The orb not as much as them.
And I'd argue those stats make it a better hybrid vessel than the Nebula. 3/3/4 is what a workhorse/jack-of-all-trades vessel should get for its consoles, especially for one with high-level universal stations. Giving the Nebula 2/4/4 without bumping up its hull even more, or upping its universal station level only serves to ham-fist it into a tanking role that the DSSV is already good at. Speaking of tanking...
The Weaver can run two Lt. Comm Engi stations, making it the best CC/tanker in the game. You can run twin EP2S III with two gravity wells! And if you don't feel like running two instances of EP2S III, you can drop those down a level to utilize Aceton Beam *and* Extend Shields. Simply put the tact station as tac team, and you really don't have to worry about shielding, given the proper doff setup.
Oh, but if you go full-on tank, then we can't deal damage! Fear not, simply switch the universal to a Lt. Comm Tac station, and now you have the same amount of abilities (and a higher power, at that) as the Recon...but with more hull and tanking abilities at the cost of turn rate. And honestly, an RCS console, plus skills, turns even a 9 turn rate into something respectable. My point is that they have nullified one of the key aspects of a cannon Star Trek ship (the Nebula), a new fleet ship's unique perk (Nova's Lt. Comm Tac station), and another fleet ship's specialization to tank/CC (Luna/Hope).
That's my issue with the Weaver. Not that it is a bad ship, but that it can potentially do a better job, if specialized or not, than most of the science vessels in the Federation line-up. And this is without touching the issue of its console and special torpedo, at that. Point being, I fear this simply sets us all up for a deluge of lockbox and CStore ships that create an atmosphere of pay to win, all because the devs will continue to produce ships with ridiculous stats while keeping or nerfing current ones.
This ship is an absolute beast, and declaring that a small decrease in absolute stats compared to the Nebula means that the Weaver isn't better is disingenuous to this problem. Also, it's bad to mention the bug ship as being "balanced." The sucker can tank like a cruiser, if setup properly, and deal more damage.
