What is so confusing ? 1 ECD is equal to $100 previous cash, which is no longer in use. If you had 1 ECD( $10,000 ) and $1000 in server before the update..they are now converted to 110 ECD after the update. So, just forget about previous cash as we are now using ECD that act as normal cash( just look at ECD as your one and the only cash in server ). After the update, there's no more problem about going to bank to convert cash to ECD or vice-versa( which the bank paid $500 less per ECD when you sell ECD. Example: if you sold 100 ECD, bank paid $50,000 less as bank pay $500 less per ECD ). But now, you do not have to convert anything because you can simply buy everything using ECD, so isnt it less complicated, easier and cheaper ? You can also deposit and withdraw them from bank as it's now act as normal cash. All the reward and everything in the server are now in ECD. Your ECD is shown at the cash's hud on your screen. Seriously, what is confusing ? it's advantegous..
What have these changes got to do with your betting in your duel, you were the one who chose how much you wanted to bet in duel..i've no words for this..
If you could spend some of your time to read and try to understand changelog regarding server update instead of confusing yourself, you might actually understand something. Btw, the commands cost will still get changed even if we didnt change currency system because most of them were not organized. The changes of currency was done to make it less complicated, cheaper and easier for us and players( especially new players ) to deal with..
