Arena-type maps.

Recently learned from Russel_lDHl about the Polish map ArenaV; I've only played it a few times, so I don't have enough experience to draw conclusions. Overall, the map isn't bad, but it has much more randomness and luck compared to TC3. The advantages are quick learning, everything is easy and simple, you play with what you get.

Therefore, it's better to play the more balanced Arena 2.4, which is clearly an improved version of the fifth arena, where blue can immediately think about which artifact sets to choose while red is still making its moves, and you can also level up 2 heroes to level 15, so that if one option fails, you can try to develop the second one as needed.

There is also a special version of the 2.4 map for HotA...
Important: you need to play according to certain rules. http://h3.ligaheroes.pl/forum//topic/8498/
