I’m new to this game myself (2,5 months), but I’m not new to gaming and I really hope they dont add any kind of trading in this game.
The main problem the way i see it, is that everyone who want to do well, and are dedicated, would have to make alot of feeder accounts so they could give resources and/or heroes to their main account. Even if you could only give 1 hero once, that’s alot of feeder heroes from each account.
If you had to pay for VIP to get this feature for heroes and/or resources, it would increase the gap between the people who cant pay (being a student myself, I can’t afford it) and the ones who can, I don’t think this is a good thing.
Right now the bottleneck is ascension items, and that’s the only reason I bother to keep playing - sure the people who pay can get alot more heroes to choose from and can choose to level up the good ones, while I have to use what I have - but atleast I can level them up at nearly the same speed as there isnt that many ascension items for sale.
The only kind of trading that would be acceptable in my opinion, would be your own resources to resources you need, for example iron to ham or scabbards to tall boots and so on.
