You need t2 burst max skills, max ore industrial skills, and max cybernetics, to have the full value of bursts.
so it can add, but it really needs a lot of SP to be worth it. Also a porpoise will do sensibly the same, with much less isk-wise.
An orca is bonused for shield and mining bursts, so you rather have eg a command dessy for the other bursts (they all help)
An orca allows you to refit or change ships on the grid, which is a nice thing if its bay is loaded with T1 frigs ^^ . Still not enough volume to store more than 2 barges so …
An orca can’t be an efficient logi. That’s because, its sensor str is so low it takes 2 years to lock anything smaller than a sun. You need to prelock everything. And even with 11 targets it’s not enough. Still, going ancil RR in the highs is a good thing, but not as good as a real logibro.
An orca needs a mwd to align in a decent amount of time. or just to move in the space. Otherwise it’s like, 30s to align ? You have enough time to commit suicide meanwhile. I mean, IRL, because that’s what it actually feels like. Yeah, most of the gameplay in eve revolves around waiting, #fun. (irony, just my opinion, don’t take it too seriously)
An orca is invaluable for boosting mining yield in HS.
In LS/NS it’s a sitting cuck, a no-go, a WTFAREYOUANIDIOT ship. Literally, I was in mining fleets and people got screamed at because they brought an orca. In null. In space controlled by us, with 30 ppl able to defend the mining operation (I was in a sabre). He did not lose it, but I was surprised we got no bombers run just to destroy it.
