I will continue to work on it until it is ready. Without too much interest from the community, it is hard to find motivation to do it quickly. I am sure ELH will be active but you need more than one unit to make things happen. So the answer to when it will be back up is probably this summer. Sooner if there is enough interest and by that, I mean units on board to use it.
With MWBU, we couldn't even get units to do basic things like challenges on that ladder. Pretty much all seemed to be waiting on the automation script that 420 was pushing for the ladder which would have helped reporting. That is working now and needed final testing. When matches had problems running this script, they gave up on the ladder which in my mind shouldn't have kept units from just using the ladder to challenge and report matches. So MWBU is ready to go except for that testing and having it installed on FCL.
I want to play league matches as much as you do man. I wish people would learn to use the ladders and play on Legends Arena and MWBU. It would be a blast but I think I am as much guilty of causing the loss of interest with the stall of the start of Season 2 of LA and the problems with final testing on MWBU.
