I've been wondering for some time now. Why did Na`Vi stop picking pudge in the first place? The only possibility that came into mind was that they wanted to practice differently for this year's International. It's been some time since I last saw Na`Vi picking pudge in an important match-up or even in any match.
Why's that then? My point is, generally Dendi's pudge always worked out well for Na`Vi, and while I do understand that they may want some other kind of game plan, why not practice the old strategy aswell? They achieved plenty of things with that game plan and when you have different ways that you can go and different core heroes that you may pick to sustain your variable strategies you only make your team stronger, both in picks and in the game as a whole.
That's of course my opinion and I hope you can express different points in order to make this a good discussion
