Even Iron Warriors don't fight like Iron Warriors, anon. That would require them to invent new tech ("Hammer of Olympia”) to fight unique problems others couldn't solve (HH1) and be very efficient at achieving 100% extermination with favorable Kill-Death ratios at the expense of munitions consumption (HH1). Even the few Thousand Sons numerologists and Order of Ruin would thrive like that. I assume TS and IW were friendly to each other because of that.
Instead, John French has them throwing people at walls. The only cool fluff is whatever you make up. You have to like Warhammer in spite of whatever GW says, writes or does.
