1.) I've read a couple places you can solo to max level in this game. That will wreck any sense of community, tell me its not true.
2.) How soon after release are they going to add the rest of the classes and races?
1.) Ok, since you asked for confirmation, it is not true that if one can solo the entire game that the community will be wrecked....hehe! But, in all seriousness, sense of community is hardly dependent upon only the degree of solo ability. Community stems from the desire of the players to form relationships and group; I have been in heavily focused group games where the group only holds together for a single or two boss mobs, then the players quit and go off to craft or whatever. Or instances where most of the game players hardly typed or voiced a word for hours of play in groups. Ergo, grouping did not lend to community there either.
To ensure better exp in a grouping situation, all a game has to have is a design to proviode a bonus exp for grouping. However, a faster killing rate in group play vs solo mostly makes up for those other games where exp is evenly or skewed toward solo players at least, that is my experience in leveling in those games.
2. ) Only QOL knows their internal schedule, but they have previously stated that player input will be taken into consideration when doing the post-release classes and after data on balance and playabilty of the release classes are taken into account. So they will hopefully be what the playerbase desires, but could take awile to get to that point eh!?
