I joined today and wanted to see if the issues OP mentioned were persistent and normal before I spent money.
I find it extremely difficult to believe anything you said here for a few reasons.
1. I logged into a Christmas holiday event complete with presents. Very cool, except it's May. Christmas has been over for nearly 6 months now. That's not what happens in a game being updated by the devs.
2. It's apparently an unoptimized mess. I'm lucky if I get 25 FPS and it commonly drops to 10 and below. On every map.
3. The lag shows a lack of care and maintenance for the servers.
Now you can argue against that all you want, but it has prevented me from spending money on it and playing it often. I'm glad I checked around here before spending money on it.
If the device are still supporting it, they're doing a piss poor job. This is as a new player that has no dog in the fanboy fights. There's absolutely no way I'd hand money to this dev team for the game. It's been out long enough that none of the performance issues should still be an issue. This leads me to believe the devs are uncaring or incompetent. Either way, the very real issues and complete lack of dev support means money from this potential customer.
It's honestly a shame as well because there's a fun game concept under all the issues. It reminded me very much of OMD, which I love and plunked a lot of hours into. Care, don't care, agree, disagree, but this is my take as a new player.
TL;DR:
"Devs are totally updating and managing the game"
If that's the case, why is there still a Christmas event running from last year?
In May?
