I'm a VERY casual player (a single character at 75 and not remotely the best gear) with a bunch of low level alts.
I love having the opportunity to complete conquests without having to do max level content. The fact is, the hardcore will ALWAYS outpace the casuals in basically whatever they do. People saying it'll take 10 minutes to max out your conquest, ok, I'm sure you can. Me? It'll still take a decent amount of time, but I can actually have fun doing what I want to do instead of feeling like I'm forced into a certain playstyle.
Obviously changes to the invasive popup would be appreciated, i don't need to see it all the time but i would enjoy having the option to.
