That doesn't work very well, for it ignores the problem of party forming. If im in a group and they decide they want to go to Natalan (as an example), if ive never been to coerthas what then? No group is going to wait until someone takes a choco to grid from uldah, to coerthas, to natalan. Or they might, it really just depends. I can foresee a lot of ppl getting booted from parties simply because of that.
Anima is very limited so its not an issue. If you're worried about ppl getting spoiled just lower the anima cap, or give it a hard-cap of 4-5 times per day (or lower, not married to this figure). You dont have to axe it altogether, ppl are way too extreme about things.
