I would looooove it if the Mass Recycler and Blue Building Spender were cumulative.
I recently bought items from both shops, spending hundreds of points, and have started building up points again. However the count on both only show what I currently have on hand to spend.
I don't think I could possible sit and wait until I were able to pile up 35000 for the Mass Recycler and 2500 for the Blue Building. The Blue Building may be possible but I couldn't fathom building up 35000 recycle points and not buy anything, I have so many items on my wishlist.
I would also love this. I'm always afraid to spend my recycle points in case another tier gets added. I'm 3k away from 35k, then I'm going to get the Illuminated Stump and hope the tiers never go up again.
OMG THE RECYCLE BEAST! This drives me crazy! I've been working pretty solidly on it for about 6 months, and I'm still only half way. It's also pretty cruel that they keep adding limited items, which only serve to set me back. Plus, they've added more tiers to that achievement twice in the last two years - how horrible to reach the top tier, spend all your points only for it to be increased further and you have to start all over again. Finding 35,000 items to hand in in line with the fickle whims of the Recycle Beast is challenging enough.
I'm less bothered about the Blue Building. I've managed that one, myself. It doesn't take that long if you do the quests every day. Just as long as they don't add any more tiers...
I don't support this idea. I think "holding onto your points even though it's quite tempting to spend them" IS the Achievement here.
If you need to always have the top tier of these Achievements and don't think you could do them again (separate issue) there's a solution. Earn even more of those kinds of points than is currently the max, and only spend those that are over that, treat it kinda like a minimum balance in your checking account to get the perks from the bank.
