Prison or ban the botters. After the initial surge went down the population seems to be be slowly ramping up now, Jin 1.0 and 2.0 were going in the opposite direction. Emphasis on "seems to be" and it is still early to tell, but adding an official bot would definitely be 1 step closer to a zombie game.
The general route to catering the working people is to offer EXP and/or drop rate boosts for cash.
Yeah, why not.
It would be convenient, but it would have a negative impact on the tactic of pushing/pulling/keeping a support class away from the rest of the group, especially since the level 7 skills have a casting time. The difference is just a few seconds, but seconds matter in combat.
That would "debuff" current debuffing (erase) skills, + what I said in 3. . Whether that is a good or bad thing too early to tell, but the erase skills seem pretty reasonable right now removing only 1 buff, so I'd say don't fix it unless it turns out to be broken.
But I also think michal211 may be right and none of what we say here matters, because from what we've witnessed so far, instead of gathering all the feedback and sending it to Korea, they could instead simply click on the feedback doc file and press "Delete", and have the same chance of the feedback making its way into an actual change in the game.
