The only reason I started playing this game six years ago (2011) was Clan Wars, and the political/competitive inter-play it would create between Clans. Clan Wars has been slowly changed to the point that it is no longer much of a draw. The "rewards" system have changed Clan Wars so much, it does not have the same excitement it once held for me. I went from playing everyday possible to not at all. Although I recently played a few games to see what the new arty changes were like.
I am not going to get into motivations for why WG has done this, I realize the North American server guys have limited influence on what decisions take place at corporate HQ in Minsk, or wherever WG HQ is. Regardless I voted with my feet during the last season after slowly losing interest and not really seeing the point to all the time put into it.
I had very much hoped WG had gone back to a more traditional clan wars system, another reason I "checked in" on the game, but no. The draw of this game to me was clan wars, the cause of my lack of interest today has been the changes to clan wars.
Playing the game itself was a means to an end, at first it was to get tier 10 tanks to play clan wars, later it became a means to get more effective tier 10 tanks to have more options to play clan wars, and finally with tank locking it was to get enough tier 10 tanks so as to not run out of tanks so I could continue to fight in clan wars, and last after I had gotten plenty of tier 10 tanks, the final motivation was to improve my game play (get my stats pulled up) to try and set the example for my clan and be a more effective clan wars player.
So....playing regular tanks day in and out was always a means to an end, Clan Wars.
Anyway these are my thoughts, and I have seen this game from almost the day of launch. I do realize it is a numbers game to WG, and players like me may be few, or not important enough to matter in the bigger picture, and I understand that too.
