I love this game.
In general battle royal is a fun aspect for me, but having the abilities to fight with swords and different abilities is quite fun!
Is it hard to understand the game? no, took me maybe 10-15 minutes to understand fully what I am doing yet I HAD and still have fun playing, manage to get first place in two matches (did quick match, my guess some are bots? can't really tell, yet some are players for sure, you can see the skins and outfits and so on).
However, and this is minor I guess, connection can be a problem sometimes so make sure you have a stable connection without something that can effect it (don't browse or download anything while playing), also I advice a good PC, because the game is still taking a lot.
So overall ? I love it, graphics are great, sound is good, weapons and the whole system is fun, I guess some heros are overpower yet it make sense, almost every game has this issues (Call of Duty with stronger weapons, StarCraft and so on).
8/10.
