You can't compare this server to any other server, there are 467 items, all done from scratch. Every map has been redisgned to allow a differnet gameplay, this is not Mir, this is like another game.
Blood Server's leveling system ends at 30, not 20. Every level up to 27 has atleast 5 items available for it. Having an extra level on this server is a major leap over anyone a level down from you. Thus being level 20, you have the power of a level 40+ on Mir, the items are nothing like Mir though.
Also don't make assumptions on Blood Server, it's nothing you've ever imagined it to be - that's why the people currently playing it like it so much, it's not the same old boring thing every over server offers. I'm awar the client is too big, but we've made the exe available to download sepearate, we've simply changed practiclly every files there is with the game.
