Hey Bloody, I'm in a similar position to you: Long term SW fan, but with my limited play in 8th i just felt like it was a loosing battle with them, and no matter how much i love the lore of SW i just feel like I'm making things hard for myself playing them. I want to be in it to win it but its all a big unknown since Covid essentially limited how much we could learn from saga.
The biggest thing over all of it the makes me want to come over to UM, which i kinda have is the fact you have to convert literally every model to make it a space wolf. I know you don't have to do alot but looking at the new blade guard, they just dont look like space wolves, and for a codex compliant army you can get away with them so im at a cross-roads now of do i leave ragnar on the shelf and go for the boys in blue or remain true to him :)
I think since i'm not one for cutting up the mini's i've sent hard earned cash on and doing lots of conversion work perhaps a new army should be what i go for... dam this childhood memories :)
