The problem I see with Elements at this point is that Zanzarino is, as stated a couple of times already, inactive and that no development can take place without a developer. That's the major problem. There are still more problems opinion with Elements.
Though it is just a portfolio project and Zanzarino had never predicted the game would become this big, this game has the potential to become so much more than it already is. It is very tiring to log in day after day to find that people are still using the same exact decks in PvP 1 and PvP 2. It's tiring to see the meta of this game never changes because the developer is inactive and can't implement a new set of cards or a new set of system to expand the amount of decks that are used. The game has room for a lot of variety and quite honestly, right now it has only scratched the bare surface of what it could be.
I bet if an update were to be added, just a small set of cards or a small change to how things work, thousands upon thousands of players would run over here and start playing again or just start playing, because something different was added or because of their renewed hope in Zanzarino. They'd know he is still working on the game, that he hasn't abandoned it.
I guess what I'm trying to get out here is that, we just need a sign Zanzarino is still here. A small post or something would help. The game itself is great, but not as great as it could be. I'm pretty much just recycling what previous people have said already.
