well, my topic is quite old already, and i didn't have much time to replay as i was busy finishing my final exams.
However i want to give it a last try.
I don't want to make people disappointed by annoyingly long mining times and levels just to be on vanilla-level again when reaching max level, but skills in vanilla minecraft are quite op in multiplayer. In singleplayer you can easily do everything by your own. Mining, farming, woodchopping, building alone isn't much of a problem and after a vew days of collecting materials you basically have everything you need. The only purpose other players have in minecraft is to collect materials even faster, building bigger buildings together or showing who's the damn boss in the server by building a bigger castle than your friends.
With my idea of this mod i want to archive 2 things i miss in vanilla minecraft. The first issue i'm trying to solve is the way how players have to interact with each other, but without these annyoing restrictions forcing you in a single job or role and prohibiting you to do anything else like some plugins ore mods do(Screw you "You can't hold an axe, because you are a miner"). Each player should be able to specialize a single skill to get quite a lot of advantages there, while he is still able to perform any action of any other skill, but muuuch slower than someone, who is specialized (so a level 300 woodchopper can chop down a while forest, while you, the mining-pro, who still has his wood chopping-level at ... lets say 12, are still strugeling in chopping down a few of this annoying large oak trees). So, if you want to make your caslte even more awesome by adding wooden floors you will have to trade your stones and ores with a woodchopper. The woodchopper now has a bunch ores needed for advanced tools, but his blacksmithing-level is quite low, so, if he doesn't want to use these stone-axe anymore, which he is barely able to craft himself, he has to go to a blacksmith, sell the ore and buy a diamond-axe from this guy.
the second issue i hate is closely related to the first one, however. Vanilla minecraft gets boring after a certain ammount of time. There is notthing you can do, if you finished your building-project you were dreaming of, if you are tired of fighting your opponents and if you have a couple of chests filled with diamonds. This mod won't be able to solve this problem completely, but I'm trying to implement some MMO-features to expand the "lategame". You are no longer a one-man-mining-machine , which is able to dig into the world and form it to your wishes. You need time to learn to use your tools and you have to found factions, make friends and trade. You can - and this is very important to me - still do everything on your own, but you need time to master your skills, while your reward for this strugge are dozens of new items. (imagine you start Skyrim or any MMO at maxlevel, wouldn't that be boring soon, too?)
