"The missions are DAMN hard, pretty much impossible to do with henches, at least if you're not a monk, forcing you to group."
That's *terrible*. I mean, to party with other people in MMORPG... Unthinkable. These "damn hard" mission quickly separate bad players from good ones and you can get decent allies fairly easily. It's not like you can ask "high level" friend to do Elona/River for you, since you're all level 20 already(or close to it). Plus, as a Mo/Me(although might as well not have 2nd class, since I only use Hex Breaker from it
) I did lots of these "damn hard" mission(except for River) with henchies. These do better than poor team who lacks coordination - but are still inferior to good team with balanced skills and expierence at using them.
I've been level for, dunno 2 days already(it's only a week since game first shown up in my country
) and I still find PvE interesting. It's challenging, unlike in numerous other (MMO)RPGs, where it's basically about continuosly leveling your hero and making sure your uber spell or weapon is enough. Here, such approach will only get you slaughtered by enemies who have same skills as you and use them well.
As for "carrot" - elite skills and 15k armor. Admitedly, something more would be nice, but hey, it's not like making full set will be an easy task. Not to mention PvP.
