I like this question!
From beta up to 1.14, most things that were added were considered improvements, so I guess version 1.14 would technically count as my favorite? I'm not such a fan of Facebook, but other than that the 1.15 and 1.16 updates were still nice.
What I disliked about 2.0 was
(1) ads, but then again, I can disable this as a member (which I do) as I feel I support WL already in different way (by bying a clan and 2 memberships). I understand the need to earn some money to pay for servers and Fizzer needs to eat and buy clothes as well in between working on Warlight, right?
(2) that the point system created a bunch of lottery games
(3) that some of the member benefits were devaluated without anything really in return (as levels could unlock almost everything now).
(4) making clans official created a whole bunch of unnecessary clan drama and a generation of trolls.
So all together, for me personally, the small advantages of 2.0 and further didn't compensate for the small disadvantage, so I can't really say it became better for me at that time.
Since I largely ignore coins and coin games for now, I actually don't dislike the update to version 3 and further. It brought some interesting things like the no-luck cycles and there were some great updates like the end-screen and alternative colours that I appreciate. Although the old community was better, the game itself is changing in interesting ways.
However, to summarize, I think I do like 3.07 now and I did like 1.14 (and earlier) at that time. I wouldn't enjoy it if I had to play 1.14 again now as many of the new features would be gone, but I probably wouldn't have enjoyed 3.07 in my early days are there are too many things I don't really like and try to ignore. It was nice that WL was still relatively small and limited at the time that I joined.
for all different versions of WL.
