Greetings. If anybody out there still interested, here's my attempt to make Seal more compatible to LW2. There's only one catch: You also need to use Shadow Ops LW2 Class Pack (I've used a couple of perks from this pack) -- https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=872274632&searchtext=shadow+ops -- If i still got your attention, just copy and replace entire mumble jumble below to Seal Class mods' XComClassData.ini file. Feel free to use.
