I came into this expecting a decently made arena, with the intent of playing with a few friends over Battle.net. Everything was fine, until I realized the map was 10MB, significantly over the allowed file size on Battle.net.
Because of the barrier mentioned above, I was forced to review this upon myself playing solo. The first problem I saw was that the map was partially wrote in German, which is against the map submission rules. I was already unimpressed before the game had even started.
Once the game had started, my attention was immediately drawn to the pandaren interface. I'm not sure how that is expected to fit with the LotR theme. Next, the tooltips. They were wrote in English, but done so terribly. The X and Y positions were off, too.
The category was also marked wrong, since the map is an AoS, and not an arena.
The gameplay wasn't on an acceptable level, either. There were only four heroes per team, each of them lacking custom abilities. There wasn't any synergy between abilities, which is a large aspect of proper hero design. There were items, but I wasn't able to purchase any of them. My hero only had one inventory space, and it was already filled with an undroppable item.
