An Alternative? to parsers..

People will find the way to abuse the system and make highest score, and this will lead people to focus on the score instead of completing the dungeon, it will raise the level of toxicity in the game, since the end results will be all depending on with who you are playing. Everyone will be pointing fingers on tanks or healer, because they died and their score went down.

Rating classes by numbers will bring even more problems than that, the rating system like this will force severe balance changes, which will kill diversity and fun coming from each present and future classes and create even more balance issues than we have right npw. Since why should you play a bard, if MCH is doing tons of damage? Buff bard, and you end up with pick-or-go-away class, that will need some of his utility and support abilities stuff taken away.
What if SE would release skill-shoot based class thats really fun to play but performs badly, due to the playerbase not knowing how to hit their spells or use properly? SE will be forced to buff its damage, to cater parser users playerbase, ending up with OP class, anyway they will need to nerf it back or flat out the playstyle.

I believe Yoshi is much more happy today, because class design is not limited by the numbers like it is in the WoW.
