I really felt that to make enough I was needing to do wasteful things that I would not do during normal game play. And that was just a test to have an idea of what it would be like to compete to win. It left little enthusiasm for that. I have 6 libraries out in my live game now to build up CC, but I still don't want to use them on useless stuff.
5m 15m productions to me are way way way worse, extremely boring beyond reason. I even disliked the 1 hour version, 3H, 9H 1 day,
I rather have VV like options.
I do not understand that you save hundreds of cc for a fellowship event, and then dislike it to use them on "junk".
On 1 of my accounts I make every single recipe that rewards 3vv or better per cc, and because I have more CC than I can spend on that I also buy for example the 10 cc for 29vv recipe and some others that have and almost 3 vv per cc.
Yes it's junk, but I love the mystery chests.
In my other city I make every timebooster, petfood, combat building and sometimes KP instants.
besides that, if you just want to play the FA with your fellows you do not need all that, if you want to play competitive and you need all that stuff and prep for it. it's not better nor worse than the old 5 minute productions with 200 workshops for which you destroyed your entire town.
it's a choice you make, to prep and go all out and pay the price for it, or play it ignore the ranking and just enjoy it. in that case the VV one is no issue at all as you do not need dumb amounts and therefore you can share the burden and it's tiny per player.
