Yeah I don't think the spinning thrusts and overheads were much of a problem, very rarely saw the overhead spinners with a great maul, and the spinning pike thrusts didn't seem like a huge problem either (just down block).
I think "turning" into your swings was too heavily nerfed, if you're turning more than 180 degrees then the nerf should take effect, but even turning 90 degrees into your stab will sometimes cause it to stop stabbing (even though the animation continues it seems like).
Like a couple others have said, and the first time Berenger posted something even remotely logical, is the real issue. The problem is if someone is standing next to you, your 15 foot weapon shouldn't be able to hit them. That's the problem, not the spinning stabs. This is the same reason it's possible to bump-couch, or bump-thrust with a heavy lance.
And I hear ya dyna, I still use my MW heavy lance when I'm playing footman because I don't want to risk losing crafting for strategus. I've still been able to do decent with it in squad fighting, but it was never a 1v1 weapon (although you can use it 1v1 and come out on top, longer spears and lances are support weapons).
