There's nothing particularly wrong with it, but it represents a huge departure from what trials have always been. Even War only expects you to complete 1 match a week. To complete 47 matches would seem to require at least 10 weeks just to be a reasonable timeframe (and 5 matches a week is a very very large number anyway). Leagues expect you to complete 30 matches over 3 months. On that pace, 47 matches would require about 20 weeks - a very long amount of time. Trials would thus go about half the year, with War taking up about the other half. Trials and War would become annual. This isn't necessarily a bad thing, but I feel like it would be a poor departure from what we have now.
