It's not just storage to store them, it's also a lot of bandwidth to host 40-50 gb clients for each version, that's a lot of transfer data lol.
When I think of a solution, I'll upload my clients in parts and give you the links to add. I'm thinking I might need to utilize my own server for this otherwise it will end in such a situation as you describe with them being taken down.
Most clients get taken down, I don't trust google, Mega etc. they're too greedy.
I agree, the clients should be given for free, but it's not the client you're paying for, it's all the transfer data required to download a 50gb client. It sucks, but they need to count the cost somehow. I personally don't agree with charging for a client.
Some people can not understand why these Aion clients can not be hosted for free. It's not a matter to earn money or sale them.
To host the clients, 100-150GB of software, plus the download traffic, costs money. There is nobody who offer you, more then 15 GB, free storage space and unlimited download traffic.
So you need to buy Mega or Google space, that costs money.
