Hey I know i new to this server but i wanted to input my opinion on this EE situation.
I personally really enjoy the use of EE and being a Mighty Mage. but i completely agree that it is way to easy to be OP with EE. On the other hand IC2 and BC items can not (for the most part) be duplicated with EE, just the raw materials that are needed. I cant speak for anyone but myself, however after a while i really hate going down and mining for 2 hours just to find a couple of ores that i need running the risk of getting exploded by a creeper or falling in lava, which happened 2 times to me already and i had to basically start from scratch. That is very frustrating, so if i can avoid that by just turning some useless junk into what i need saving time. I still have to do a lot of work to build IC2 or BC items which i plan to do.
If Minecraft is not a game were there is not a clear objective or a straight winner or loser, you should then not get comfortable just focusing on one aspect of the game, there is so much you can build, so why limit that? Yes there are people who go around dicking around with their loads of EMC, but dont take it out on people who dont do that. So far i really enjoy the server and the people on it, and i personally wouldnt like to see it limited at all.
