I don't really think they will be changing warriors just to improved low level game play. From the comments I've read and the gm responses I've gotten, I get the feeling they think everything is fine.
When I first saw that Hamstring was now a level 26 spell, I sent a question in asking about this. I tried to approach it from both pvp and pve angles, since I know Blizz's focus is not low level pvp. They have said that they want to keep people excited about leveling. I made the points that not giving warriors a snare could be problematic for all those mobs that tend to run away and spark a chain reaction pulling other mobs. To this they responded something to the effect that the change of HS, the addition of MS/SS/BT, Victory Rush, and the change to HS should increase damage to a point where you shouldn't have to worry about runners unless you are pulling too many mobs or ones that are too far above your level.
I also pointed out that not having a reliable snare is in BG's pretty much gimps a class that has to be in melee range. Charge only gets warriors so far. Being put in combat or outranged is death. Without hamstring, we have no way to keep opponents close. The answer I got was essentially "Piercing Howl is available at 19, use it." When I brought up the fact that is not a solution for sub level 19's and both Arms and Protection, I got a "lower levels are going to naturally be at a disadvantage and each spec has it's pro's/con's."
I would be shocked if warriors got any of their utility spells back for low level use.
