As much as I cherish the English language, I don't think there's a rule against run-on sentences or grammatical mistakes here. Nor is there a rule against pointing out difficulties in understanding each other. I think it's good to provide useful advice to help people express themselves more clearly, but at a certain point you just have to let them go on and be ignored if they're really so difficult to parse.
I mean, if most people are going to breeze past an indecipherable post, there's no real need to call attention to it. Believe me, I understand the frustration, but pointing it out is only taking more away from the topic at hand (and here, look at me doing just that!).
Now, to get back on topic for a moment. The thing I'm looking forward to the most today, as silly as it sounds, is Vergil getting pause combos. I thought his moveset was rich enough in DMC 3: SE, so this is just icing on the cake. I'm actually happy about the prospect of it being hard to go back to 3.
