You're joking, right?.. even more individual damage and resistance types??
The game has more damage and secondary effect types than it needs already.. on the contrary, they (the devs) were unnecessarily hard working in terms of creating all this mess..
Just keep ADCtH............... and omit vitality, life leech and health reduction damages all together.. that's what they should have done from the beginning.. ah, also most of the secondary garbage cheap effects such as petrify, immobilization and freeze should also have been thrown into the trash bin while only keeping stun and slow.. they are nothing but extra and meaningless burden on the shoulders of players..
Why would I want to reduce the health points of a satyr, fire beetle or a tigerman, when I can already put them down in 1-2 hits anyway? why is this effect still in the game if its not gonna work on the things that it should?..
Ask yourself simple questions such as these, and you will easily get all the answers you need in no time..
