@TWICE I don't really use either much; I generally go on TJR with Gauss + Aries. That being said, when not on TJR I take out a Vulcan + Dictator, which I use for close combat (it's surprisingly effective).

Unfortunately, alterations are now 245,000 crystals each. That being said, I do get the general idea of what you're saying. Thanks.

I have to say, I kind of liked the old client better. As @JESUSaves2 pointed out, the new client uses a lot more resources. So much, in fact, that it sometimes crashes my computer (which is saying a lot; I run a quad-core i7 desktop with plenty of RAM.) Also, I liked the layout and feel better. Specifically: Being able to access Missions from in a battle Easier access to the Battle List (MM is fine, but I kinda miss Esplanade) Not having the Battle List's scroll level reset every time you try to get information about a battle No red outline on tanks when you are targeting them. It makes it impossible to camouflage your tank, something I used to do quite often. Shaft. That's literally all I need to say. Just "Shaft". No thirty second loading screens.

So, by careful saving up, I have accumulated 20,000 crystals. Unfortunately, I don't know what to do with them. Therefore, I put the question to you, the Forum Community: How should I spend my crystals? Keep in mind that I am currently at Warrant Officer 2; the things you are suggesting must be available at or near that rank.
