Pub Tier list on DotaBuff (Article)
Competitive / Pro Tier List (Article)
Discussion / Observations:
There's actually a trend AWAY from heroes with Primary Stuns. The number of disables that a pro team drafts in general has gone down. Heroes with longer-range disables are favoured (Gyro missile, Wyvern ult, etc).
"Skillshot" spells are still very popular (Tusk Ice Shards, Lina LSA, SFiend Razes), although different from before (Pudge, Mirana, Earthshaker are less popular)
Trending towards semi-carries as supports, or offlaners as supports (Tusk, Undying, etc). Emphasis on early-fight heroes and tougher heroes and supports (use of Bounty Hunter, Dazzle, Bane, Ogre, Earthshaker). Squishy supports are much more rare. Emphasis on roaming supports in the 4-position that can "make plays happen".
Flash-farming carries are much more popular. Anti-mage is still somewhat popular because of his ability to get ahead in farm once he gets core items. Carries that can do well throughout the game are favoured (SFiend, Ember, QoP, Alchemist).
