Long ago I made a post regarding the one time usage of the TMs. Which is everywhere, even in the regions from generations, where they be used infinitely, apperantly.
It received the reply and was locked later.
Now, the reason given why they're one time usage, is because of economy in MMO.
Now, I've never seen someone selling TMs, but I do see people gathering them, manually, through game progress. And surprisingly, you lose the one you used.
I also do not know why TMs need to be dragged inside the economy, just to maintain economy.
I think that is somelike toxic.
First of all, here are a few reasons why one time usage is bad:
When you use it, it goes away. This makes it really bad for people, that are trying to test their pokemon and the attack. It's stupid if because of that it goes to waste. And this can be repeated multiple times, until you go bankrupt.
I believe MMO is great to battle against other players, in a Pokemon Game environment very similar to the original one. To get more advanced you require a good setup of Pokemon and thus have attacks. Now imagine having to setup or test Pokemons with one time usable TMs.
Confusions in certain region of generation versions, where they are ment to be infinite.
I wonder if there is a TM, that can not be reobtained by any seller or anything else. And if such an item would be sold, the seller needs to buy it from someone else, which is stupid, because like his profile can not get the unique TM anymore, if that even exists.
So yeah, those were reasons.
I think TMs should be changed.
Let me know what you think about it.
