I quite liked the original 15person method of grinding mobs for skill.
But then we were shifted from that to leves, then from 15 to 8 people.
And now leves will become more solo-orientated content.
It feels like we're being shifted from box to box without any diversity.
I read the producer's letter and saw thats was he wants to move away from and provide various methods.
But right now there is nothing to back up those words. We have 2 upcoming instances for 25+ and 45+ on a cooldown (unknown?).
And I very much doubt in the intial stages many ranks less than 50 will be given a spot if the instance is how its been quoted as "difficult".
So that leaves the other instance.

I'm not saying the current static selection of leves that most rank up on isn't monotonous, it is. I'm bored of it too.
But I wouldn't take the benefits of that away without having something immediate to replace it with.
