I seriously can't believe this guy is trying to defend the skill so badly to be 2-3 minutes long, it would still have the same problem at 2-3 minutes as it not all that hard at all to be doing your own thing and check back every 2-3 minutes, it would still be AFK farming going cause if people can abuse it, they will.
Standard attack time is all we need for upward shots, 3MP cost can be left alone for all I care, I just want it to not last forever. It making the class I like playing look bad, anyone can look at me now and think I might have possibly cheated to my levels when I did the work myself instead of abusing it, meanwhile another cowboy degrades it by AFK upward shot abusing to stupid levels without any effort.
