It's a global dmg reduction, most likely to reduce dmg at myth pvp and since it's a global modifier honor is effected, which shouldn't be the case, honor is unplayable now for most of the part and about elite, it took 9 full combos to kill one mage elite vs elite. No point. My theory about this is that since cinco told he's bringing arcane set that will reduce damage output and since it's taking time to develop he adjusted the damage instead for now.

And this global dmg reduction wont solve myth pvp, seriously. Auto dmage (arcane boat) is too high either lower it or reduce the range significantly or both.
I mean really what in the world in PL a high auto damage bow got 13m+ range?

2- No point rhinos almost all damage at one combo, it's ridiculous already and since even after dmg reduction rhinos will be still able to do 2hit kill because of that the difference I can clearly see will be more, rhino 2 hit kill (one combo) and it will require more skill to kill rhino.
Again what in the world rhino is doing 2 hit kill since L100 pvp?
