Not sure if anyone is aware, but the godmode, or GM, used to be.. Well, good. Ie: you wouldn't ever die. Ever. Only when the plugins were reloaded.(if you happened to be in lava, or TNT, big fall.. Etc) Then, Zerg made a new godmode, whic wasn't bad. But wasn't good. Basically, it gave you 100 heartsin front of those 10. So you had extra health. That.. A lot of moderators didn't like. The only reason: death whilst grief.
I personally lost, with that godmode, 6DB and roughly 9 stacks of ironore. Tp'ing to flyhsck alerts, and those 100 hearts failing on me. I know Merirox lost some, as he was the leader of The Hamptons(expensive). The point being, it failed. Not to mention, remaking diamond and iron swords, compasses and pics every time we died.
Why am I telling you this? Zerg doesn't like the GM in which you don't die. I don't blame him.. That's why he made the other GM. bukkit limited the amount of hearts you could have, to 20. That's it. Just 20. We can't use his, and he dun' like the other one.
