At least with Teclis and Kairos, it's safe to say they are heavily discounted and substantially better than an equivalent character you could make from the armylist. I'm not so convinced about Thorek as you give up a lot of handy runic options to get that powered up anvil. I'd probably put him in the 'more balanced in 8th edition than he used to be' camp. Tec and kairos are probably the only SCs I'd look to outright ban in this edition.But as a general rule of thumb, any special character that screws with the magic phase in any meaningful way is generally a red flag. I think the main three (Teclis, Kairos, and Thorek) are an easy concencus because you almost never see a Hard Boyz list without them, which is also a pretty big red flag.Possibly this is more of an issue if the opposing army is built around deathstars? For that reason alone, I wouldn't have an issue with him. It's no different to a player losing because they shaved points on standards and then rolled blood and glory as the scenario; they made their list, now they have to play it regardless of the scenario/opponent/first turn bad luck.Finally, like I said earlier, Skarsnikt is mainly an issue because of his reserves thing, which makes it really hard to balance certain scenarios around and randomly wins entire games if someone has over half their army go into reserve. If he did not have that ability, he would not even be a blip on the radar, really.
