It would be helpful to have a larger capacity for the blacklist, or even better: remove the limit.

Someone who only plays through MSQ and does regular activities would not need more than the 200 slots allowed. However, players who participate in high-end raids and frequent party finder, especially through multiple expansions, run into a higher frequency of unpleasant and troll players that you would not want to ever run into again. They may not be stalkers but they no less make the game less enjoyable.

As a player who frequents high-end raids and plays with hundreds of people through party finder across each expansion, I find myself needing to remove older players on my blacklist in order to add new ones. It may sound excessive to some, but it's necessary to prevent trolls and other unpleasant players from entering my party finder. Blacklist is a very useful tool but over time it becomes a revolving and I can't remember everyone I don't want to play with, as well as it is tedious to manually remove someone from your party after they have entered every time you make a new party finder.

I'm sure that having a larger or no limit blacklist would improve the gaming experience of many players across all data centers and servers. I hope this can be implemented one day soon.
