I'd have to reread the specs for AO, but I was under the impression that not all dragons were evil, ergo not all their followers need be.
Assasin could use a bump as a prestige class, but that's neither here nor there really. If you limit SD to any one faction, however, you're basically just going to have a large relocation of the standard one level in SD cheese to that faction, possibly unbalancing the factions a wee bit.
Limiting the cleric domains is an interesting idea, but if you place limits on travel and trickery (the cleric cheese), you're once again going to see people go where they can to get both. Melee is just weakened without haste; it's as simple as that.
Alignment restrictions could be interesting, but I think the devs wanted to allow some latitude still to avoid a whole faction's being 'sploded by scythe wielding smite monsters. It might enhance roleplay, but it's gonna hurt when a worked up build can one shot your 30's char.
@ Milkman -- I think the reason TC and MA are underplayed lies partly in the failure of people to properly utilize the buids that can be worked up from each. Palemaster can be quite nasty when done right (who doesn't like lots of immunities and a cool bony arm?). Same with shifters from the circle -- shifter has been very nicely worked on, and it will take a while for people to experiment. As to why TC and MA never have relics -- well, MA might be b/c the run out there is utterly horrendous. NC, I'd argue, has the same problem though. From SL to Daeron was at least 22 mins last I checked, working the haste as well as I could. That means it's going to be close to an hour for a single relic run, and any competent defender/spoiler can just hop ferries to steal your relic before you even get to Melencia.
I don't agree with adding rogue to TC as I haven't seen what the new shifters can do with some Rogue in them. I'd really hate to see sneak attack dmg massivley multiplied by a vampire form or the like and a new reign of cheese start. Also, the Circle itself would not, in RP terms, support forest brigands or Robin Hoods. There are freakin fairies dancing around Melencia -- it isn't a rough and tumble frontier city
