While I agree that 7 players is a lot (I myself would not want to DM for more than 6, and my preference is for 4), it's hardly unreasonable. The game system should be able to handle it with no more than a moderate slowdown. Hell, I remember back in the day playing in 2E games with 8+ players; the largest group I was ever in topped out at 14! Now, granted, things were pretty bogged down at that point, but the game could still move. Try to imagine a 14-player combat in 4E.
Yes, exactly (emphasis mine).
In my group of 6-7 players some of the slowness has been due to players vacillating about what powers to use, but I've encouraged them to make decisions more quickly and that has helped some, although not fully solved the problem.
I think it really comes down to monsters having too many hit points in relation to the amount of damage PCs do. This is compounded by the fact that each class is now assigned a different role, and thus limited to the qualities of that role. For example, wizards have no or few spells that can actually do a fair amount of damage to a single foe. In other words, it may be that WotC simply didn't get the proportional relationship of damage to hit points quite right.
Maybe "grind" is the 4E version of "15 minute adventuring day". Some people notice it all the time and it bothers them, others don't notice it or aren't bothered by it. Should definitely be an improvement point for upcoming WotC products, be it in better adventure design, better DM advice or new Monster Manuals.
The +1/2 level damage, -25 % hit point and +1 level damage and -50 % hit points "mods" should probably be added into the character builder.
Good point and I think you're right (again, thus my
Annie Hall analogy). And, as you imply, regardless of whether it is a "different strokes" issue, enough people are bothered by it that it should be a major consideration in the future, if not in upcoming 4E products (which we would have seen already), then for 5E or, gods forbid, 4.5E.
But yeah, I like the idea of adding the modifications into Monster Builder, although it isn't absolutely necessary as you can scale monsters up and down by level and role already. That Solo monster have too many HP and is a bit too tough? Change it to an Elite. Too weak now? Raise it a level. And so forth.
