Because it takes resource to make improvements. If there is stuff in there that isn’t used, and stuff like shouts - which is easy enough to lift out without impacting a reasonable amount of people at all - which has never worked as it was meant to, that can be taken out, then this frees up resource that would be use on these parts of the game to be repurposed to other areas of the game, where there have been problems for a long time, but that a much higher percentage of players actually use. I’d much rather they made the stuff they’re keeping work properly, coherently and immersive, than use create a club - which is far better done in the editor anyway, or play a challenge. The only feature they’re removing I’ve used is shouts, and I don’t use those that often anyway, and a lot of it can be circumvented to a degree by changing instructions anyway.
It really is far too early to be making any judgement on the game when all we’ve seen is a load of words, 2 screen mock ups, and a bunch of mocked up tiles and cards.
