I’ve had Starlink for over a year now. The best answer I can give is that it’s been a roller-coaster over that time, and that will likely continue. When I first got it late last year speeds were fantastic (200-300mbps most of the time) and latency was even better than cable in most cases (20-45ms).
But the service experienced a slow degradation, with things bottoming out around late august / early September or so. Service has improved since then and is pretty decent right now. It’s a constant balance between the number of users compared to the number of satellites as well as the number of ground stations. The number of subscribers has already more than tripled since the beginning of 2022. Service also varies from area to area depending on the number of users in your area and the number of ground stations in your general area. Service is also generally worse during peak hours.
I think that they just got a bit ahead of themselves expanding service so quickly. And there have been some other shenanigans. Right now home-based subscribers are limited depending on if your “node” (general area) is full or not. If it’s full, you get put on a waiting list. Well, Starlink began to offer mobile/RV service, which is not dependent on any node being full or not. So lots of people signed up for mobile service just to use it at their home instead, bypassing the waiting list. Starlink also started to offer “best effort” service, which basically allows you to subscribe in an already-full node, but your data supposedly gets lower priority. So the Starlink network is really getting pushed to it’s limit in some areas.
Most of the satellites in the current constellation are version 1.0 and version 1.5 satellites. These are both similar size and mass, but the v1.5 satellites have some extra features such as being able to communicate with each other via laser, making them less reliant on the presence of a nearby ground station (they can relay data to another satellite instead if needed). They are currently launching new v1.5 satellites as fast as they can, to keep up with new subscribers.
But the real game changer will probably be the version 2.0 satellites. These are over 4 times larger than a v1.5 satellite, with significantly greater capabilities. The v2.0 satellites themselves have already been designed and are ready to go. The only catch is that the v2.0 satellites are too large to be launched using the Falcon 9 rocket that is used for the v1.5 satellites. The v2.0 satellites require using SpaceX’s new “Starship” rocket, which I believe is still going through some regulatory/legal hurtles before it’s approved for usage. Some of these legal hurtles are being introduced by competitors simply to delay SpaceX, which is very petty and a real shame.
Right now I would say that WoW is playable on Starlink, but it’s not generally as stable as most landline connections. You can “feel” the brief lag-spikes sometimes and it can be frustrating when those come during critical moments. I’ve even been disconnected on some occasions, which is obviously not ideal if that happens during a M+ dungeon or during a raid boss fight. But it was a LOT better back in late 2021 / early 2022. Back then it was basically flawless (indistinguishable from a good landline connection), so it should be possible to get to that point again.
Using Starlink is a bit of a gamble right now because we simply don’t know what the future holds, with technology issues, legal issues, and even political issues all mixed together. I’m optimistic about what will happen when the v2.0 satellites start launching however. SpaceX has said that Starlink should eventually be able to provide speeds up to 10Gbps. Who knows if that will ever happen, but it does show that the intention is for the service to evolve far beyond what currently exists. If anyone can pull it off, it’s Elon Musk.
I’m not sure what your Cellphone situation is like, but WoW really doesn’t use much data. You could always use your phone as a hotspot and game on that as a backup option, if Starlink is being unusually bad on any particular night.
