I always found thinking of warhammer, or magic the gathering, or any tabletop game as truly competitive to be somewhat counter to the spirit of things. Its something I want to do with my friends or people I know at the hobby store, I want to be able to put together something interesting, that while it might not win every time will at least create interesting play. Now I understand that's not how everyone sees the game, so with warhammer, i play smaller formats mostly the skirmish rules, and with magic i never play constructed decks, because i get steamrolled by people who take it seriously as a competitive thing. I play either sealed or draft because everyone is on a levelish playing field given we're all only there and then choosing cards rather than me having looked at what i have out of my previous draft decks and trying to make something fighty, where someone else will have specially constructed theirs to mirror whatever the top playing deck of that moment is.
I think if you want a fluffy game, campaigns and smaller format games are the way to go, or ask around at your game store, if anyone else wants to use fluffy armies rather than uber competitive ones. Either that or accept you're going to be running nothing but screamers of tzeentch for the foreseeable future.
Competitive gaming isn't for me, If i want to do something competitively i just get punched in the face
