How to make gathering storm more appealing
Make it scale with level instead of time (maybe something like level 6/11/18) and lower the bonuses it gives. The mastery is underwhelming right now because games are ending so fast and you can't really make use of it. If you make it scale with level, you will have control over it and you will be rewarded based on your performance instead of getting the bonuses no matter what. What do you think?
