The problem that brought down the old Warhammer Fantasy was exactly what made it popular among its fans; a tactical, complex game where well-organized armies of a vast amount of models clashed. Thus you have a game that recruits extremely slowly - a huge cost of entry, not only in money, but in assembly and painting as well. (Remember, eBay sales do not do anything for GW, and have never been a viable option in many parts of the world, including mine.) No game can survive on a tiny number of extremely dedicated fans if the parent company is as big as GW, there is too much overhead. It seems GW saw the myriad posts proclaiming that the hardcore tournament scene had long since moved over to WarmaHordes and thought, "well, if that's the case - why are we even catering to them?"
Some thoughts on the system:
The players who seem to get most out of the points-less system seems to be those who follow the idea that the setup system is a part of the game, where battles can be lost or won at the staging board, so player A puts down a monster, player B positions a unit of cavalry to take it down, player A responds by placing a unit of spearmen to counter their charge, and so on. Any attempt to make limits on wounds, warscrolls, etc. have seemed to make matters worse. I predict that units that are straight downgrades of others with few or no special rules to make up for it, such as a clanrat being worse at everything than a stormvermin, will simply be fazed out in favor of units that are somewhat comparable to each other. Sadly, as a multitude of troop choices makes for a more colorful game.
As for the odd positioning, remember that all movement, including rotation costs towards the limit, and that no single part of the model can exceed that - so rotating the model is a fast way to waste 2" of movement. Still, weird model positioning seems to have been intended in the system as they wrote it, and I am worried about the state of my bases - I usually spend some time making them pretty.
The setting:
I, as probably one of an extreme few, actually like the new setting better for wargaming use, as I always had a problem placing the endless number of battles fought with the limited scope of the Old World. I have spent some time studying the map, trying to figure out just how two armies would march across three hostile realms each, including through narrow passes and past mighty fortresses, just in order to fight the battle the players had set out for them. I love the Old World for RPG and Skirmish use, the WHFRP 2ed will provide many an adventure in years to come still. If it helps, think of the Mortal Realms as "Heavy Metal Fantasy" - an over-the-top excuse for fantastic costumes and lyrics about smashing skulls with a big hammer for the glory of Metal, or in this case, where towering einherjars smash the skulls of murder-cultists with big hammers for the glory of Sigmar.
For now, I still await the actual next edition before making final judgement, things might change. The base question is one I suspect is subject to this, as the current rule has a "we-only-do-this-so-you-wont-have-to-throw-out-all-your-old-models"-feel to it.
