Something has to be done about the server instability, a crash now and then is to be expected. But at this time we are talking about 10-12 crashes per 24h, if you need to upgrade the hardware/bandwidth or w/e please set up some kind of donation option in order to counter this major issue. Same goes for the input delay which also is a result of the overwhelming server population.
And please, no ignorant comments regarding "latency" which is something else entirely compared to input lag (hardware cap).
