100 Armor + 100 Health = 200
The nex does 130 Damage.
48 Health + 22 Armor = 70
Armor = Health.
Now to the balance problem. Mega and Armor are exactly as in other games, which doesnt fit to nexuiz imo. The weapons do more dmg and we also have a lot more splash(+splash through walls) weapons, which makes it easier to damage the opponents (and teammates

You are able to take 25er healthpacks and get more then 100 HP with it. I am fine with that, as it is an unique part in the game. But it reduces the usefulness of the Megahealth a lot. In other games you cannot get significantly higher then 100 health without the megahealth, which makes it that powerful in these games. The usefulness gets also reduced because of the rotting (losing health over time when above 100 health), as you have most of the time more then 100 health before you grab the MH.
**EDIT** Because of the replies, I splitted this thread into 2 Parts:
1.) Balancing the Armor / Megahealth compared to the damage output of the weapons.
-> Is it needed?
My suggestion:
Make the Megahealth 130 Health
Make the Armor 130 Armor
I think that would balance them against the weapons and combos (nex damage = 130 // nex+mortar combo = 165-195 damage).
2.) Improve the MH somehow? (see divs post)
- > If you had the choice between the armor or the MH, most would take the armor. GreEn`mArine pointed me at the map final_rage, to call one rare exception.
Discuss please.
