I'd much rather see tiered instance content with longer lockouts so we can actually get items vs. 10 stacks of dark matter. I played the camping overworld raid bosses for years as a top guild and while it's great for the top 1-2 guilds on the server, it sucks for everyone else. Trigger mobs are just a band-aid and if you're going to do that, why not just have it instanced in the first place. The only argument I can see for it is because it limits how many people you can take. The days of zerging bosses down are long gone.
