4th edition and hit points

Alright, after a long hiatus, I'm thinking of taking up fourth edition to see how the rules play out. My first feeling, and this comes from having played 4th at three game days, is that the monsters simply have too many hit points. The length of time that it takes to kill goblins is ultimately ridiculous.

So, in running the game, I have decided to halve the creatures hit points except in key encounters. I expect that this will affect the game in the following ways:

• Encounter powers: Since each encounter is technically half an encounter, I'm only allowing characters to recuperate powers after every other encounter. They may still rest so as to use healing surges. This will mean that encounter powers will have to be used with some discretion. On the other hand, creatures will still have their encounter powers. This will, I think, make for more and more interesting encounters as their will be more creatures gone through in the same ammount of time, with the same number of cool effects.
• Minions: minions are likely to become more powerful. After all, they won't lose half their hit points so they will remain the same power level while everything else goes down.
• Strikers: Strikers who do 25 points of damage and etc., will be more effective at killing things in one shot, however, they're likely to find a lot of the damage they do going for nought. This takes striker's power down a step which in my opionion, makes them as attractive an option as all the other characters, who are kind of less worthwhile than strikers as they stand right now.
• Controllers: Particularly wizards, are kind of a joke with effects that last until the end of their next turn on dailies. Who cares? One turn? Battles with creatures who have 120 hit points are going to go for too long for that one turn to really matter that much. However, if the creature has half as many hit points, controller effects will matter all the more.
• Looks like AD and D: In my opinion, Advanced Dungeons and Dragons was a great game with some problems. Subsequent additions have done a lot to fix those problems at the expense of taking away a lot of what made the game great. Dungeons have gone from forty rooms with a bunch of interesting stuff to five. By halving the hit points and experience, you are doubling the number of encounters the characters get between levels, the size of their adventures, and the number of encounters a party can get through in one session.
