So i asked the devs this as well and am still awaiting an answer but would like to see what the community has to say on the matter as well. You see i myself (and it would be foolish to even think im a minority with this opinion) does not wish to play the legions given to us at launch. And lets face it, it would be wishful thinking to see the 5th warband be a god specific one. So we will be forced to play these legions we find no interest in. And i do not protest out of the simple fact that the devs need to focus their attention on the core of the races to feel good and to play good. Adding in more legions should indeed take a back seat to actually making the game at launch present Chaos in the most refined badass way. What i want though is that when the time arrives and the devs grace us with our desired legion (Death Guard ftw) that we, and anyone who wishes be free to just swap legions. No hassle, no stat and progression resets, nothing that will hinder our effortless transition to the legion we wanted to be in from the start. How they go about doing this, i thought of the following: The progression of the class will be point wise imo. So when one changes his faction all his spent points return into the point pool so he can make his choices anew. This could be an item given by the devs for free or for ingame resources each time theres a newly released legion. After a certain time (like a few weeks after the legions launch) it could just be put in the games shop to be gotten like any cosmetic would. Which brings me to the only issue, being the cosmetics you unlock/buy up until that point. They should logically just transition with you and simply have the colors of your new legion forced on them, but something like the helmet cosmetic of Khorne would be wierd to transition to someone whos playing a Thousand Son. So it would either need to be auto-swapped to the respective gods helm (of the legion that you swap to ofc) or change to the Undivided version if someone perhaps swaps from those god specific legions to Undivided.
