Well, let's say a few words where it all went wrong here, too, shall we? It's really not hard, though, it's gone wrong since day 1. Because during vaultbuilding I didn't see much of anything, I asked for kdz' grand plan and got nothing. Well, we still need a vault, don't we? *sigh* Guess I'd better get started.
So despite planning on tagging along and learning a bit about whichever team I'd wind up in, I wound up building vault myself... With no prior experience in team Fire in war or sharded wars I just built some staple Fire decks: 2 Immo rushes, 2 Fire stalls, 2 Fractices... and then got to thinking what original ideas I should think of to complement Fire's weaknesses. They were Voidbolt and Catitan to counter Bone Wall, and NT rush to deal with Lightning/Shockwave. Which is all fine and dandy, except the only deck proposal I got during vaultbuilding from others was an RT splash from kdz, which implied the RTs coming from salvage, meaning none of it had to be included in vault. Both elk and xn0ize popped into team chat at least once to discuss vault, but the only changes made from it were 2 Short Swords and a missing Nightmare.
And then war started, initially it was just sending decks in vault to the appropriate opponents based on bias alone of course, with no games played we had little to go on in terms of prediction. The only thing I knew certain was that Death would bring Bonebolt :p But, as rounds progressed, I ended up building decks, handling salvage/discard, making predictions, testing the decks, etc... when my war app explicitly mentioned I did NOT want to spend more than 3 hours per day on war. So I had to cut essential steps for winning war: no vault intel, bad predictions, minimal testing... These kinds of things are the difference between victory and defeat, obviously. The decks I properly predicted tended to be decks re-used from previous rounds: constantly re-using the same decks makes it (relatively) trivial for your opponent to predict and counter them.
The one round we 4-1-ed I was like: screw it, let's go crazy. So I decided to build decks completely by my own style and going all out on craziness right up until the round we were eliminated. The main reason we were eliminated that round was that I had little choice but to re-use old decks at that point: vault was pretty much fully used, save for a few Fahrens and Deflags.
Perhaps next war I should make it more clear on how I don't feel like doing all that crap by not doing it, though that shall partially depend on whether I join it and as which role. I apologize if someone thinks I made a fuss over something at any point in war, but doing WAY more than planned and still losing had me rather annoyed throughout war. Of course, like I said so far, it was not all that surprising.
