168K tickets lost since the start of this strat versus about 925k lost in over 8 months last strat. Simple Math: there were 5.5 times MORE battles, lost troops and gold, in those 8 months than in nearly 6 months of this iteration.
I would say there's quite a few reasons.
First: AI By having AI you ruin and make it far more stale for everyone. Last strat, the voting system was nice because clans could, within a week get into a war. With the AI: it took at least 2 weeks just to get started(depending on faction, of course).
First day: 17 Feb > First Village Capture 22 Feb. 6 Days before anyone was able to take a fief.(I believe it was only 5 on EU) The first castel was done 1 month later.
Second:
Prices: By upping the prices you decreased combat capability further and for the most part, have removed an entire class out of the game. This leads to point 3
Third:
By upping prices you forced everyone into lower tier gear. By forcing people into low tier gear, the only thing that people REALLY had going for strat, the XP, was nerfed into the ground.(it has since been addressed, but 4 months to late)
Fourth:
Tydeus. (Not really just him, but he's the poster boy) I know many people who've gotten fed up with the recent buffs/nerfs breaking stuff far to much.
Fifth:
Age of game
Sixith:
(on the EU side) Stale, repetitive. Nothing has broken the Endless cycle of alliances
that are their every single iteration. (For those who can't count, or are new, that's 3 years of EU effectively fighting on 1 side together against the exact* same enemies EVERY. SINGLE. ITERATION.)
There's Possibly others, but those are the ones I've seen the most. Go ahead and sound off on anything you think killed strat.
EDIT:
Where Am I getting that 925k tickets? That's coming from the old thread I made to keep track of the NA wars statistics back in 4.
http://forum.melee.org/diplomacy/the-great-na-war-losses-to-date/The Start of that war was counting was February and lasted until it's termination sometime around December. Strat had been ON GOING for 5 months previous to this.(Sept-January which is before records date.)
