Yeah I'm not the biggest fan of them to be honest. But also most of the Leviathan minis are kinda meh. The terminators are great but I'd like the full squad with all the options. Especially given how everything is priced with all the options rolled in now. The character models are beautiful. Aside from that, from the space marine side, it's pretty much a pass for me.
The lion model will be the same, it just won't come with bladeguard veterans which you may or may not need for your army. Either way you can buy them separately.
Looking very good!
