That would take just 3 weeks to hit the 35k cap because 7k a week is easily doable from about an hour or WQ each day. (14x3 is 42) Some days less some days more. This isn't doing everything that is up but just whatever is up at a specific time. The costs are really not that high if you are actually engaging in the world the content. The upgrades open up more world content which you are not even doing in the first place.
People are putting this weird importance on Anima when they don't even do the content. A lot of the expansion is set up to encourage more open world content and a lot of the people complaining about anima are not actually doing that content anyways. The items that off world content buffs, dailies, WQ's, etc that all appear from the upgrades.
It also over looks that souls are the limiting factor. If you have gained enough anima each week to buy upgrades you could have two level 3's and 3 level 2's this week. That means we need 8 more weeks of souls to buy the rest of the upgrades (154 at 15 next week and 20 each week after that). That would put you at 112k Anima by the time you have souls to buy the upgrades if we just double the rewards across the board. The remaining upgrades only take 47k more Anima.
The anima is there is people want to actually play the game. If you don't want to play the game then there is little reason to have enough Anima to buy the upgrades (or cosmetics) in the first place.
