So.... with that sugg :
We can't use meat shields anymore. Aka peasants getting onehitted, and you swinging before the ennemy finishes his strike, so being able to hit him freely.
This is, imo, a very good tactical slash, and if you had this dead players absorbing hits, then spammers will prevail. Just kill someone in front of you, other people will bounce off the corps, and you can continue spamming to get the other one.
So... or you make this "temporarily" VERY VERY small, so double hits will not result in tk, and we can still use the strategy mentionned above, or just no.
If you're killhungry, then karma will get you. Learn to know how many hits are needed, and to quickly block when the ennemy die, and this problem will be forgotten.
