I have a question about the stealth errata. In a game with precise positioning of tokens or minis on a battlemat how does one "guess" the location of a stealthed target? Looking at the battle map it would seem pretty obvious.
The same issues come up with invisible targets. They go 'off' the grid, and people that know where the character is has to track that information. The game I DM has a drow as a PC, so I need to be able to bring up a darkness cloud when I need it. It goes behind the DM screen, and only the drow gets to see where characters are. For the monsters, I would use a random roll of which adjacent square they attack, assuming they don't attack the last square they thought someone was in.
The DM should remove hidden monsters from the map an put their position on a secondary grid [we use modules, so I put them on the map in the book]. The players have to guess where it is, based on where it disappeared from, how fast they've seen it move, perception checks, etc. As a DM, I have to decide what the monsters would do, and not take my knowing where the character is into account. So basically, if the monster would assume the character didn't leave the square they were in, they would attack that square, otherwise they would try to find a better target. If they have to attack a square and they aren't "sure he was there a minute ago" I would roll, probably a d8, and have him attack one of the squares next to him [eliminate squares he knows aren't viable targets].
I think the biggest problem rogues have versus the other strikers is not the problem of gaining combat advantage every turn, but the fact that a lot of the places you have to go to get combat advantage are quite unsafe. Flanking a guy sometimes means standing in the middle of his buddies, who then smack you around.
Meanwhile, the ranger is shooting arrows from 40 squares away.
