Well, i don't really now what i should think about elements 2.0, so i will just write down the consequences which I thought about and let everybody decide for herself/himself...
1. Splitting it to 1.x and 2.0 would result in some things: The enemy-system I want is in 2.0, and the cards I have are in 1.x. I finally got my first fully upped deck, and i don't intent to train a new account to the top if the elements would split. I would play for some more time and then stop because I now have two accounts, and neither one is completely satisfying (The same happened with me with diablo 2 and diablo 3, and the same with Elder Scrolls: Oblivion and Elder Scrolls: Skyrim) That may be only what I would do, cause not everybody is the same as me. i would estimate that about 10-20 % would quit from that.
2. Would 1.x still get updates? If not, it wouldn't get the new cards anymore, and you would have to split the arena and the pvp after all. If it would get updates, Zanz would have to put all card-updates and pvp/arena updates always in both games. (i don't know how difficult this would be, (or if it would be as easy as Strg+C and Strg+V) cause I am not a programmer after all.
3. If there would be 1.x and 2.0, because of the new false god system (and the impossibility to farm false gods the whole day) and the new NPC system, people will start to argue about which of the two systems is better. I think they would split about 75% to 2.0 and 25% to 1.3x (because it gets necessary to create a new account as well...) If the elements 1.x wouldn't get the new card updates, we will slowly lose about the leftover 20-30 % óf gamers.
4. New players by 2.0. It would make a new game at kongregate and other sites, so it may attract some new and old players. I can't really estimate how many these are so it gets difficult at this point. Maybe about +20% to +40%
5. Players which play more than before if the elements is splitted. I think if it is splitted, some players will play more, and some players would play more if it gets a clean 1.4. So that may be even.
From the things I listed, it's difficult to make a decision which is better. So I want to hear other arguments and your opinion on my own arguments, to make things more clear. And something else: I hate fighting. And something else: All of your arguments till now were pretty poor because you focused on fighting each other. Focusing on your own arguments and thinking about the arguments and oppinions of others is a more mature way to do things...
