Exactly. In my opinion TWF got too good overall, and I always wanted to see it nerfed because it was imbalanced in my opinion.
I still want to see TWF and THF / ranged totally equal in cost and in power. I am very experienced Dungeon Master, winning some contest in the past, and I know that's not how D&D was built. But in D&D DM can always adjust everything behind the curtain and no one will ever know he wasn't transparent about it.
D&D 3.0 and 3.5 was just very imbalanced, because it didn't even need any balance beyond being "believable". If you delved deep into rules, they were really not that perfect. That's why most good DMs modified them to better suit THEIR campaign.
Here, Turbine has much harder job. Well, 1000x harder job that average DM ever had. Especially when they could go Warhammer Online route and never have complaints about Warhammer rules, be it miniature s's or RPG-game's, because Warhammer Online... just doesn't use ANY Warhammer rules
.
That's why I'm worried and almost sure than next DDO MMO may be just Forgotten Realms fluff, some random dice fluff and... no D&D rules at all. Or just very little of them.
But back to the topic - yes, this is TWF nerf, and not only TWF nerf. And it may help lag a bit, but was never intended to fix it. That was clear from the start, Turbine said it themselves. They just didn't say "hey, we want to nerf TWF". Well, they're not that suicidal, I guess?
