Defense formula was fine for the level 70 just had a few issues with low levels which could be fixed.
What everyone is complaining about was the critical damage, i believe it wasnt that wrong but it could be decreased.
I think everyone forgot how TW was, SKs had CC aura, 39% jacket and buff and still got hit kill sometimes. Its fun to see full %ABS LP SKs crying about getting hit killed, get the right gear and it wont happen. I could tank even with healer that doesnt have 25% buff.
SKs arent immortal, it is normal to die sometimes, they always died for fighter when got a crit, thats why they always tried to get maximum anti crit and p.def in TW.
What i am trying to say is that the hit kills from fighters, turtles etc are because of the critical, not the defense. This defense is to put a difference between +15 and +10 etc and to fix some damages that were a bit incorrect. Without this formula +15 and +10 have the same damage and same defense, you have no reason to upgrade higher than +10.
For the ones that are saying this formula was made only for dojo, i have been working at this for a long time, a lot before dojo was announced, even before mudosa points were fixed.
