Tobe Honest I played every thing but inquisitor. With that in mind I would say that BFG was the only game that didn't have serious problems. I mean blood bowl if you played seasons is one unlucky thing happens and your team sucks, winning the first two games in a season and bam you will continue winning. Why because you will have the beefy destroyer team.
Necromunda and Mordheim were the same way except with them you honestly needed a GM with a super warband/gang. Like at first enforcers are the control, but then you need spyers when gang shenanigans go too far. With mordheim take one of the web developed warbands just stat them out with a bunch of XP and stuff and they will be your games spyers. In all honesty if you look to gw for game balance you are looking at the wrong place.
The one thing I am always bothered by is how prevalent a painting competition that golden deamon is. Sinceas a competition goes you have to purchase GW stuff to participate. I think truly open painting competitions where we can see Warmachine, Ultra Forge, Alkemy, Malifaux, Iron Wind, Reaper, DragonForge and all the others participating against each other Ithink those deserve more props so to speak.
