do quests NEED to be done?

just wondering is it possable to like get everywhere on the map and get everything and beat the game without doing the quests??

yes it's possible

i blast through the missions to get ported to the next town asap, and if i feel like doing the skill quests, i do those.

missions have to be done, but quests do not.

Team missions are a good way to get to the next town fast. But if you like to go on your own and explore the map rather than getting to the next town fast, than its also possible to travel the hard way

Just remember that you hardly get experience without quests/missions. So its not entirely possible to do it without quests: you need to level now and than or it will become too hard to continue!

Yes and you get items and skills for doing quests so I do alot of them

this is not true. as far as i know, every mission is accessible via explorable areas, which means that, at least in theory, you can run from outpost to outpost through Explorable Areas without doing the missions.
the only one that I know of that is definitely required is the Academy mission that gets you out of the pre-searing.

I think you need to complete another one . . . sanctum clay or something like that to cross the ocean to amnoon oasis, but I suppose you wouldn't have to do every mission

you are wrong

you cannot get to the crystal desert to ascend unless you do the mission to get there then you cannot ascend unless you do 3 missions then you cannot get to the fire islands or the tomb of primeval kings unless you complete the missions that take you there.

you can skip a whole bunch if you wanted to, but imo it's a hell of a lot easier to get from one place to the next by doing missions. You also get 2k xp and a skill point per mission, so i'd say you'd have to be either a glutton for punnishment or pretty stupid to not do the missions.
