monster placement & diversity : Ver 2.0

Like the title reads, in open field environments (ver 2.0) what style of monster placement and diversity of said monsters can we expect?

Currently in ver 1.x we have "puddles" of monsters. It's very un-organic (is that a word?) In spot 1: Ants Spot 2:Fish spot 3: beastmen spot 4: higher level ants 5: higher level fish ect ect....

In ver 2.0 will the placement be the same, or can we expect areas to be populated with mixed mobs?

I'd rather like to experience more diverse battles where on a "pull" you have a variety monsters to battle. Making priority targets to burn down, things to CC, stuff to off tank ect ect.

I would definitely love to see different placement of monsters...and maybe even change the way they are now this kind of mob mentalility where you have 30 monsters all jumbled all over each other...maybe cut that amount in half and adjust the respawn rate...this may even lead to better exp parties and such...and hopefully the same principle could be applied to the strongholds...reduce the amount of beastmen, spread them out more and adjust the respawn rate...kinda like how it was for the beastmen strongholds in XI

i would like a mix of both. some area's with mix mobs and some with groups of mobs. Will will defo have same mob group'd area's tho since im sure there will still be strongholds in 2.0
