If all of you like playing Kanna, then you shouldn't cry about its damage. It's just a game. If you want a DPS class, look at a chart.
I'll give you example. Imagine that you are working in a good job that you like. Now suddenly they cut you 60% of your salary. Are you gonna try to explain it or you just keep gonna work because this a job which you like? This is your logic, and the salary in this case is our dmg. Kanna need dmg to be viable on the new 230 lvl content that they are currently introducing. And we won't change class because it's not that easy to get Arcane Force.
Numbers are not a problem for me. If all of you want more damage, then spend more money on cubes for better potentials and crap. If Kanna can't do anything anymore, then use it as a mule. If you only care about damage, which everyone in this thread cares about, play another class.
nexon should also remove Kishin and make Frenzy Totem the only thing for mob spawn increase thing. That way Kanna will be more competitive. That'd probably make it fair for everyone.
A better way I'd prefer is if you'd get the rewards automatically, provided you have space, or let us open it in DIPQ.
Getting the rewards automatically would defeat the entire purpose of keeping you alert, watching and clicking, instead of grinding mindlessly.
I think the best solution would be to have DIPQ (and Evo Lab as well) not hide the notification icons. They should behave like, say, Commerci Voyages, which keep all the notifiers but disable specific quests that could teleport you out of the map.
