The quests in this game are no more of a grind than WoW's quests. If you consider questing as grinding then i guess it has grind since this is a quest-based leveling game. But grinding in the more traditional sense of f2p's - without even having quests to fill your xp bar (forcing you to only kill mobs) is practically non-existant in Allods untill the mid thirties level range (and i hear that is fixed as well).

Also, there's plenty of quests with much more flavour than the usual Kill/Collector quests. Seriously - level your toons untill after the Igsh Military District in the Empire and you will see the quests have a lot of variation.

Plus there's special quest series called "World Mysteries" that span through several areas and when completed give you a Ruby to use in the grid system (the equivalent to WoW's talent system).

However, if you are burned out of the traditional leveling system of questing then this game isn't for you because it is quite traditional in that sense: you need to read the quest text to know what you are doing and if you don't read you won't be immersing yourself as much as you could in this game.
