I'm about to change my opinion, because I had a while to think about it, and after a VERY long chat with KRD, it was that long I started out completely sober, and ended up drunk lol.
But anyway, I still think WA is in it's prime, but to me, WA has always been in it's prime, it's never ever once got worse for me, i've always found it the most exciting and fresh game i've ever played, and the biggest part of that is with the people I play with, alot of good friends and players have left, and alot of good friends and players have been made more recently.
I think one of the reasons WA has always stayed fresh for me is because I switched a dramatic switch from playing only Warmers/Ropers to playing only BnGs about 6 years ago, then about 2-3 years ago we started b2b, then just over a year ago we started a2b, and then I joined TuS.
I like to think I have always went with the flow, I always usually complain and/or panic when something big changes in the community, but I always end up either respecting it, or absolutely loving the change.
About all the good players that left, most of which were "Ropers" when you think about it, some people say they left because the way the game was turning out, but I think some of it was a chain reaction, once some of them left, their friends got bored having no one to play with anymore and didn't wanna do anything else with the game.
For me, the game didn't kill Ropers, Ropers leaving killed Ropers.
As for your statement about clanners flex, I don't judge my opinion on statistics, there are around 10-15 clans with extremely good players that could easily reach the top 3 spots if they "wanted" to, but most clans play for fun, and sometimes screw around in-game and play drunk n stuff like that, which is cool I guess.
TdC for example, look at their members, they have talented players that can cover every single scheme and I think if they wanted to they could reach the top 3, but they don't care about points n standings etc, they just play for fun (obviously they try to win but fun comes 1st imo for them), but they are still a great challenge and very relaxing/fun to play, you always get a good conversation/laugh with TdC.
Other clans, I respect because of how laid back they are and how fun to play with.
But that's just me, i'll always love this game, and although I really miss alot of players we've lost, and things are not the same, I will always look at it with as much of a positive view as possible, that's why I think WA is in it's prime for me.
