The most rational explanation for combining the tournaments is so that NGS guilds don't feel pressured to recruit 14 out of 50? roster spots dedicating to a tournament that happens four times a year. However, I feel like having only 7 out of 50? participating in a GST is going to create a weird GST atmosphere anyway. 43 other people aren't going to be humble enough to just sit out, so it's either going to encourage new and temporary guilds specifically for the GST (which is the exact problem the NGS should be fixing) or it's going to leave people feeling unhappy. I'm not really sure how the best way to handle it would be.
