I looked at the changed greg has made and I am quite pleased. First he has fixed cells picking up lava. Remember how slow it would be and you had to click on a lava block that wasnt updating? Well now he fixed that and you can just pickup tons of lava much faster now. The enet is being worked on by player but it NEEDS it bad. 1.5.x is filled with enet problems and issues. Right now ic2 is in dire need of fixing and I am actually excited greg will do good. Even though he is kind of a megalomaniac he seems to know his place here and thats to squash bugs.
Myeah, reading the commit progress is leaving me carefully optimistic atm.
