I can see where you are coming from.
My goal was to make the Trans opaniel weapons the "epic 2.0" meaning good for damage weak for survivability.
I also feel like upg weapons do have their place in this system, its a one time purchase you never have to pop spirit stones (outside of trans stones if you got em) whereas that opaniel weapon is going to need constant upkeep. If predator katar mastery crit rate was removed 3.0 katar still becomes best in slot. A trans opaniel katar has one main advantage over the 3.0 katar that being the stats you can get over 500 agi on a trans opaniel katar depending on your reinforcement lvl and 250 agi stone.
Having said that I have made some changes as follows:
1: Opaniel Transcendence Health changed from 100% to 60%
2: IM attack stone changed to 50%, IM DD stone changed to 55%
3: Arena warrior's DD stone changed to 45%, Keena's Collected S-Stone (Magic) has been fixed to 45% magic attack
4: Arena Warrior/Assasin/Mage accessories stats changed from 25 x/y/z to 10 X/Y/Z (a +12 earing would now give 85 X/Y/Z instead of 100)
Thanks for the generous offer, hopefully the GMs take a look at this.
