Huh? I play Viper on keyboard and mouse and it feels absolutely fine to play. Also, this job unlocks at level 80 and we're at level 100 in the game - is there a reason to neuter a job just because the job is a little difficult? There are only two things you need to track with this job. The first is its ?/100 gauge and the second is the time left on your Noxius Gnash debuff. This job is even easier than reaper.
