I think the new platform was almost certainly launched too early. It has way too many bugs and especially interface problems. Not being able to name cards that are not available in supply and other bugs that make certain cards near-uplayable are serious problems.
But the interface problems are even more serious. There are several, but the most important is the buttons in the log. During beta testing, I didn't for one minute think that this (to me) temporary solution would actually be implemented live. A tutorial might have mitigated this confusing UI, but there is none.
I'm not complaining about these problems because of how annoying I might find them myself. (For instance I know about the buttons in the log, so this doesn't create a problem for me.) I just want to say that these are things that should be fixed ASAP. The longer until this is fixed, the more casual players will be driven away. Delaying launch would probably have been a better idea business-wise.
