In using Nano Armor, it seems to make me almost impervious to damage, and only *slowly* drain the energy while doing so. I can sit in lava for a minute straight and have lost less than 5% of the energy. I thought monsters hitting me did some damage once or twice, but for the most part their attacks do nothing.
This is on a bukkit server, using Forge 220.127.116.11 on the client side, and craftbukkit-1.2.5-R4.1-MCPC-SNAPSHOT-174+r4.1update0721 on the server side, and IC2 v1.97. I have some other mods, but tested with IC2 only, and got the same behavior. Previously, in Minecraft 1.0, with IC2 v1.43, it seemed to work fine. It was strong, but damage still got through, even if it was just a half heart per zombie hit, and after a lot of heavy fighting, you needed to recharge it. Here, it feels extremely overpowered, and I can't use it in good conscience. (Incidentally, yes, I mean nano armor, and not quantum armor)
So, is this by design, or is this a bug?
