Zombies that lethal after zombie modifiers added (Bosses not included)

Yes, this is my 2nd blog post, admins will bear if they added badge for writing 3 blog posts. So... I want to post what kind of zombies will be lethal when zombie modifiers attained.

List of the lethal zombies

• Shambler: N/A, except for noobs with only 0 Heartburn, which in this case, Apex Fiery Skin Regenerating Berserk Shamblers Elite.
• Stalker: Apex Fiery Skin/Poisoned Limbs Berserk Extra Strong Stalkers Elite.
• Spitter: Apex Berserk Chitinous Hide Fiery Skin Spitters Elite. Yeah, deal with it, we two got rekt in Power Out. Apex Berserk Extra Strong Acid Blood Spitters Elite.
• Runner: Apex Extra Strong Dark Minion Berserk Runners Elite. (No, not my thought, but this one) Seemingly the 2nd hatred for me.
• Bloater: ALL OF RESISTANCES, DARK MINION, REGENERATING, EXTRA STRONG AND EXTRA FAST, ACID BLOOD, PLUS APEX BLOATERS ELITE FOR THIS ONE! Shortly, Nightmarish Apex Dark Minion Regenerating Acid Blood Bloaters Elite (But wait, Nightmarish zombies will ignore 5% of your armour protection), since they sometimes comes in crowds and they're from everywhere, going to kill you. I hate this zombie if they had this.
• Shielder: Apex Chitinous Hide Regenerating Extra Fast Shielders Elite. Why Chitinous Hide?
  • Physical weapons can't hit Shielders comfortly, unless you flanking.
  • Shock weapons, like Trailblazer and Gigavolt can arc to sides, unless it have Energy Resilient instead of Chitinous Hide.
  • Thermal/Chemical weapons, still, didn't do well to Shielders, but what it lacks in physical attack (Poison Claw indeed.) it makes up in its DoT. Since Thermal lasts for 2 seconds while Chemical lasts for 3 seconds, let say, Apex Shielders vs. Stripper, and as such, Apex Shielders have 3000 health (But wait, that's 150% Apex Stalker's health...). (225 * 3) + (1500 * 3) is 5175, so say goodbye to Apex Shielders, provided that Shielders don't have Poisoned Limbs.
