The +1 building is very welcome. I've been playing since the beginning and I still don't have all buildings upgraded. I've got lots of useless defense buildings to finish.
Anyone who has an iph of 41mil can finish this without much problem. Not to mention that many of the new players can raid the veterans for billions now.
And just to be clear, if gree was going to put out a building for vetrens, a lv1 would cost billions. That would be a welcome challenge.
