I don't know if I am the only one, but back when I was playing a few servers a few versions ago I noticed mob spawn rates were much higher. ANYWHERE there was light level of 6 or below, a mob would spawn. I had to make sure I had my houses, bases, etc...very well lit, glowstone here or a torch on the wall in that corner because if I didn't then a mob would spawn and sometimes kill me. SO far in this server, I have cleared vast areas of land, underground, above ground, made towers, trying to get monster to spawn naturally so I can go hunting with my pack of dogs...but man I get like 1 or 3 spawns tops.
My next point, having the server difficulty harder, or higher spawn rates if they are turned down for some reason, creates a sense of immersion. Immersing one into the game, where if you are building or digging around your base and there is low light, you either better have your torches being placed, or checking your back for spawns. That gives a sense of excitability, not knowing a skele will spawn and shoot the hell out of you and kill you or not.
I feel this request should be sincerely considered and reviewed. This is not a game-breaking plug-in request or anything that would affect peoples play to a sever extent. The peaceful players who are builders and possibly younger kids that just like to build, would not be affected if they take 1 second and put a stack of torches in their inventory, or learn to wait till daytime to go out gathering flowers, lily pads, wood, etc...however it would satisfy gamers that like to be adventurous, actually have to gear up to go out gathering if someone was serious about not dying.
Also, I would like Fedgar to reconsider the safe death system, I actually hate being babied and not ever losing anything...the balance between risk/reward is absent in this game. There is never a risk, and only reward. "Hmmmm to try and place blocks down across lava to mine that gold ore...or pass it up, decides to mine gold ore, but then is shot by a skele and falls in lava!...but wait I dont ever lose my diamond armor, enchanted bows, swords, pics, shovels, or mined ores...so no biggie" I would rather fall in the lava and lose half my items or all of em, and be pissed but LEARN a lesson and try to become better.
TLDR: No read the post, dont be a lazyass...
