Thank you for the effort Taem but in this Median , the merc itself having some huge self-regeneraion itself which he only can die from high spell damage spell or 1 hit KO spell and continuously high Physical damage barrage which can be counter by using teleport on struck proc.
When your merc still alive when u enter a game he is in the Median merc state which is very powerful and having high regeneration but when he died and revived back he in Diablo II merc state which is weak and low regeneration. When he in weak state he can easily die to the point u have to give him some potion u stay alive which is very troubling. Its just to better restart the game or rejoin the game to make him in the Median merc state.
Thus being said heres my commends on:
1. Healing a Merc : Does not needed in Median state.
2. Merc Damage : Mostly your merc do damage to normal monster and in median community, pvp is absurd since it does not balanced to fight other hero.
3. Vitality and Mana : Merc dont need it.
4.-Working Effects: Item removed for Prevent Monster heal. Usually u dont take your merc do the all the killing just to get high mf drop by combining your merc mf to the account.
5. High regeneration merc does not need life leech.
6.The critical hit its only 5% which is practically not important because u deal damage to monster not player.
7.The Act 5 merc's normal attack has 2 hits which is why u can see double thunder slam.
8.When merc at max level he in state all max resistance which does not needed any res equipment.
9.Well Poison damage hard kill him maybe because of this.
10.Sorry i dont understand what is BreakPoint and maybe it does not needed for survival capabilty since this is Median.
11.+Skill for merc is useless. Hes dumb anyway.
12.-Is LAEK or LL better for this merc/worth MO'ing? I dont understand what is LAEK or LL and teleport on struck in the onthing that worth MO on merc.
13, 119 for sp 120 for mp which u can just see his exp does not increase beyond that.
14. Well the merc cant use skill other than his own skill, so any buff skill on him would be good.
