The Rogues largest weakness is it's horrendous Fort and Will saves and there are very few things to help rectify these. My major suggestion for these is to max your Stealth and not be the target of such attacks. They also suffer from MAD having to spread their points across so many abilities to be effective in combat, skills and saves....it hardly compensates for the classes weaknesses.
The more people complain about the rogue's combat effectiveness, the more I want to play one...
there are numerous threads on it. the rogue is probably the weakest class in the game.the main method of damage sneak attack gets out passed by upfront damage from 2h weapons.
yes a rogue can use a 2h weapon he will just be bad at it. the rogue aside from very narrow circumstances will never be a good damage dealer compared to say the fighter. I like the rogue thematic in story and fiction. the clas is just bad at doing that in a way that is meaningful to how ALOT of players play. those issues can be accommodated because games should be tailored for the players and their characters. but ALOT from Internet posts do not seem to and one of the classes big strengths has been de emphasized.
I was simply trying to say that getting a 24 ac at low levels is not a an overpowered thing because it hardly compensates for the classes weaknesses.

The Pathfinder rogue had its sneak attack choices increased dramatically. So its very easy to deal fighter or barbarian levels of damage. This of course requires a flank, but in a party of adventurers its only the fools that dont work to get the rogue a flank.
The weakness of the rogue is the same. To be a combat monster it needs the help of a flanker. In solo combat a rogue will never equal a fighter.
As for the comment that a rogue can learn two handed weapons, that would be a huge waste of a feat for a rogue unless he plans on fighting with a flanking buddy in which case he might as well take levels in warrior.
A rogue with flanking buddy using a greatsword will fall way behind another rogue wielding two daggers.
