Simulator hotfixes are rolled out
the results of strawpoll are visible here:

53% were for pre-tourney, so the changes will be pre-tourney.
39% were for post-tourney and 8% were against any fixes at all.
According to my tests these changes should change up the ideal strategy by quite a lot. The two main things that you will have to test and tweak are your player builds and teamfight positioning.
The changes are:
1. Magic Resistance and Armor buffed by a lot. Other build values tweaked by a little bit.
2. Teamfight positioning mechanic was buggy before which resulted in staying behind as the best option. This is fixed now.
I thought this to be a moderately fair amount of things to change before the tournament. Let me know how these changes fare up, I have changed the sandbox limit per day to 75 for now.
As far as future goes then I'd need to decide concretely on whether to slowly tweak on this simulator, try to make the best of it or try and come up with an event based simulator from scratch.
Good luck and have fun!
