This game has plenty of different quests, though most of them end up as usual - Kill this kill that or gather this gather that.
What I find the most uncomfortable about this game? Well let me think about it..., probably a lack of info on Active Skills under the Path of Envoy, which is a part of skill system (skill system is kinda divided in 3 parts + stats), this Path of Envoy is ~ripoff Path of Exile passive skill tree, it is actually the very same but you don't improve it on each lvl, also you got active skill here which divides into "You can use this skill with your main class weapon + *this* weapon" which can be few different weapons which you will be able to wear if you'll get a secondary class with this weapon, which you can choose on 40 lvl (haven't got there yet myself, but pretty close) and none of those skills display any dmg/cooldowns/as/etc. and you can't even view how it works or what it does whatsoever, the only way to find it is within youtube and still without any description, hopefully that will be "fixed" when the game will be released (currently it is in OBT phase).
As for the soloing in this game - it is pretty easy, the only thing I couldn't solo so far are dimensional bosses and not because they are so strong, but because you simply aren't allowed to solo them, thus I have omitted them for now (you should be in a party of 3 to start the stage).
And in the end I would like to mention that I have already established our Guild over there
