My normal pattern is to just do my 10 a day to get my own crown chest.... but last time I would try to win enough games to keep my four chest slots full.
This time the heavy hitters were on vacation or something so we weren't filling the clan chest as fast. Since I was mostly baby sitting file copies anyway, I spent a lot of time playing. The nice thing about the clan chest week is that it seems like folks don't play as well. I actually made it briefly up to legendary arena last night.
I was number 2 for the clan chest... and got mostly trash. I took a screen shot to remind myself next time what time investment actually means.
...and I like this post because for anyone who doesn't play the game, 90% of the above is total nonsense.
