Partly because spice is too sparse right now but mainly because...it was absolutely gorgeous in the Forest. It looked beautiful in that backdrop. I can't believe it was disallowed in there; it was absolutely one of the prettiest things in the Forest. And it would definitely help new players get spice since the Forest is one of the main areas newbies come to. [There is a whole thread in the forums about how difficult it is to get both spice and gas here.] And then we would have at least three areas that allow spice; right now spice can only be REPLANTED in two places, Ix and Jethimadh. It seems as if each area needs about three staple kinds of tree, and right now, it's seriously messed up balance-wise, or there wouldn't be a whole thread about spice vs. gas. Of course, eggplants are a bit different as they tend to pop up wherever there are caves and dark bits; and paper trees have special spots and we can't plant or kill those anyway.
Here's my suggestion on the basic tree types per area, based on what it is now with possible tweaks. I went over this carefully to get it so that no area would contain exactly the same three types and so that each type has FOUR areas to grow in, for now, of the possible 10 areas (not counting Baqala and Choru for obvious reasons). Right now we have too many places with bubbles and not enough with spice and gas, for example. Also, wood is so short-lived that I think it'd be all right to have it allowed in more than four places. This suggestion would make sure of some equality but lots of diversity:
Alakol: bean, bubble, wood [eggplants in caves, as is]
Bortola: bubble, fruit, wood
Chakra Phool: It's mainly eggplant right now. In fact, I don't think gas or spice actually grows here (as mentioned in the spice vs. gas thread). I pretty much only see eggplants? It's such a dark area, eggplants make sense. Could always add wood as again, it is just too short-lived not to have "extra" spots. Or just use this as an area to balance later on, if we see a need for things that isn't being met.
Groddle Forest: fruit, spice, wood [eggplants in underground spots, as is]
Groddle Heights: bean, bubble, fruit
Groddle Meadow: bean, fruit, wood
Ix: gas, spice only—since the area is small anyway; doesn't seem like it needs three types, and there are plenty of other spots for bubble trees.
Jethimadh: gas, spice, wood
Kajuu: bubble, gas, spice [eggplants in underground, as is]
Shimla Mirch: bean, gas, spice
Tell me if my math is wrong, but that would put no bean at less than four growth areas and no area with the exact same tree mix. But even if this particular mix isn't adopted...
1. Please make sure that the types of tree have equal main areas, whether only 3 or 4 or 5, etc.
2. Oh please bring back the spice in the Forest. It was so beautiful there with the dark rich color in the shady areas. :)
ETA: After reading b3achy's note, if Shimla is to have no patches, then Chakra could be bean, gas, spice (eggplant). Why not? :) And just to be clear, I'm not saying the players should try to keep that particular tree mix; I'm suggesting an idea on tree allowables to the devs. Naturally could be done in a variety of ways, but I was trying to suggest a good mix of both variety and balance:) My 1. and 2. above are also requests to the devs, not the players:)
