Mmmmm, I have to conclude that you misunderstand the nature of tactics. Tactics isn't about a +1 or a +2. Tactics is much more than that.
Please there is no reason to get condescending just because I am disagreeing with you. There are multiple levels to tactics.
I didn't actually claim it did, I was mentioning Stinking Cloud there IIRC. The point is none of this gets at the point, which is that the new FS motivates monsters to move, the old one doesn't in as many cases. New one is more about control, old one is more about damage. The point holds.
I have already agreed there is more motivation for monsters to move away from the moveable zones if they do their damage at the end of turn. But were we disagree is that there is significant motivation for monsters to move anyway away from the original beginning of turn zones.
It is perfectly OK to give wizards a few daily powers that do moderate damage in an area. Players should be choosing the style of wizard they want to play not completely limited by having their damage options nullified. They shouldn't be forced to be pure controllers.
The changes to Flaming Sphere seriously downgrade its damage output for a minor increase in control. Also the fun tactic of punting monsters next to the sphere is gone.
The changes to Stinking Cloud seriously downgrade its damage output for a minor increase in control and a big loss in tactical flexibility.
My group used to use it as a moveable shield against ranged attacks as it blocked line of sight. Now it is only heavily obscured, sure this is 50% protection against ranged attacker but the cost of using the moveable zone is move actions on the wizard so you lose half your speed and may have to spend twice the time as a target. Suffering twice the attacks with 50% protection is roughly equal and another tactic has little value and gets flushed down the errata hole. Lets not forget that it now of no value at shielding from area of effect attacks as they aren't affected by concealment.
If WotC feel the need to rebalance these powers fine. But they are also killing some of the fun tactics players used with these powers and that is bad for the game.
While we are rebalancing things can we please improve some of the marginal options.
Web would be really fun if it affected creatures that moved into it. No dashing through the web anymore but PCs and monster could be punted into it.
Wall of Fog would be much better if it was movable or larger in size. It is far too easy to move around.
