I think new class has better skill than old and it is unfair arena battle between new and old classes.
Reaper skills need to improvement:
Reaper 3s stealth
KUNOICHI or SURA 6s stealth
Reaper no super armor grab resisted skill (soul spike can make)
Kunoichi (rain of steel) or Sura (shadow break) super armor grab resisted skill
Reaper no grab skill
Kunoichi (suplex) or Sura (shadow strike) grab skill
Please see reaper and rework it.
