Many people do not have a good computer to play minecraft, version 1.9, 1.10 are quite required in terms of graphics. If possible and please allow access by 1.8 would help a lot. Thanks in advance.
Here's a tip to solve your lag (maybe).Yes. These versions use a little more graphics, Optifine does not help, the server could adapt plugins for version 1.8 also version 1.9 onwards it sucks. The PvP is not that great, added the 1.8 PvP option but it is not the same thing. This server was pretty full, with the change of version began to get less players ... Listen to what we ask! If the server returned to version 1.8 without a doubt I would buy the best vip!
The owners and higher staff have made it clear that they will not be making the server 1.8 compatible nor will they be making a 1.8 version of the server. All I can suggest is that you use the latest optifine with everything set to as low as it can go. If that doesn't work, then I suggest searching the internet for possible fixes. If all else fails, save for a newer/better pc.
