Well I may get bashed here for bringing up another game but here goes:
I played Asheron's Call for near 3 years, it's a MMORPG that was encouraged group play by giving a bonus, such as the Synergy bonus in NS, to those who grouped. The more in the group, the fewer xp's you get for each kill; seems reasonable and to me it worked out well. Then some started making the same statements made here, "Why group when you can solo and get more xp per hour". So the devs beefed up the xp per group. Then the complaint came, "The monsters are now too easy for groups and the game has no challenge unless you solo". So the spawns got beefed up. Then the complaint was, "Well some of us don't have the same time schedule as others and soloing is the only way for me to play". So the devs then added multiple dungeons with lower level critters and faster spawns. Then people started 'camping' the spawns and griefing lower level players which the dungeons were designed. So the devs created level limits to certain dungeons. Then the whole 'critters are too strong issue came into play'. So the devs beefed up buff times and added another level to buffs to make them stronger. Then lo and behold "The monsters are now too easy for groups and the game has no challenge unless you solo".
Full circle I saw this go round and round for three years, give or take a few things I left out. Thing is, Asheron's Call started gaining a lot of powergamers and loosing a lot of the RP guys. No biggie to me, I for one liked to solo cause i was one of those who has a screwy time schedule. But for others the game became too unbalanced and the whole community thing went out the window. The game started loosing popularity and AC lost a lot of long time players who PAYED to play, every month. Which in turn caused MS to develop AC2 which bombed with a vengence.
Look, nothing lasts forever. Enjoy the game and remember, the NS4 still isn't complete. NWN, in my opinion, is one of the greatest games out there and to give the end user the ability to customize, heavily, and go PW with it is just a blessing. I never got into DnD pen and paper but wish i would have. It was just kinda nerdy when i was a kid and i would have been shunned by my peers. But now that im an adult, I can play video games

Enjoy what you have. The xp distribution is fine. Some areas could be made with super monsters so group play is the only way to get to the goal and some areas, from what i understand, will be designed simply for Epic Characters in the final version. Just hang tight till then and if the critters are too easy, make a new character that isn't so UBER but fun to play.
