It just ruins the fun. When one team takes the Elder Dragon, it is essentially a guaranteed win. I enjoy being able to just brawl constantly, but once one team gets elder drake they do so much damage that the other team has no chance. It makes snowballs snowball even harder, and I feel that comeback games are the most fun experience to be had in ARURF. A lot of champions still need time to get going even in ARURF, and elder drake actively prevents that. There are many champs I would love to play but they just don't have the time to scale into late game and as a result the champion diversity is reduced. I really hope someone that can do something reads this. I have many more thoughts on the subject but its way too much to put into a post.
