A “competitive” Skaven army at 2,500 has over 325 models. Magic is so goddamn broken that the whole thing becomes an exercise in selecting your wizard, some magic item combos, and the 200-300 ablative wounds for him. The 8th ed. rules are a hot mess, some weird attempt to synthesize fluff and competitive play that screws both mentalities over in the process.
Again, I don’t play, so the plight of FB- while lamentable- is purely academic to me. But FWIW, if the rules were good, I'd totally have about 3,000 in VCs and maybe some Skaven on my shelf right now.
However the fact that some of these same great minds are now working on 6th ed 40k, now that worries me.
