-Do you want story-missions that are profession specific or not?
It would be nice to have missions that are profession specific, maybe giving a profession specific reward item.
-Do you want side-defined missions, or missions for everyone?
I would prefer side-defined missions. PvP is an aspect of the game that is optional, to an extent. I know people who have played for a very long time and have yet to see a player from the opposite side. If the majority of the story missions were side-defined, then running around trying to figure the mission out would be the main concern, not constantly looking over our shoulder to see if an omni or clan spy was sneaking up behind you...
-Do you want the quests to scale with your level? (So you may take the same mission at lvl 30 and at 100, only with tougher opponents?)
Yes. It would be nice to be able to go through the fun of the mission, regardless of what level you have made it to.
-Do you want many small, or fewer longer quests?
The more story missions, the better. How about doing some smaller one and some that are much longer? The more there is to keep us thinking, the better.
-Is it ok with you to camp spawns, like we see in other MMORPGs?
No. Camping is one aspect of mass rpg's that is really irritating. Rare spawns should be shared by all, not a few that choose to hog it.
-Is it ok with you if we interweave the normal auto-content mission system in this, so that we can generate areas for you even in these story missions? (Or do you want only outdoor action?)
Yes. Interweaving the auto and story missions would be fine. Like I've said before, the more there is to keep me thinking, the better the game is. I've been doing auto missions for so long, I've learned to take each one as a role playing experience. Being able to use the story missions with them would give us more role playing opportunities. And, as far as this player goes, role playing is most of the fun, no matter what level your character is.
