Better even, many Arenas nowadays SHOW how big explosions on the ground are with handy dandy circles on them, that are TOTALLY not the same size as epxlosions that may happen, it's weird! (Hades, second boss in Troia, P8, P6, too many fights to remember but many of them do, even thallsballs have a short shockwave that shows the size of the explosions, just kinda hard to see sometimes)
HOW would people know that arenas have markers on themself sometimes and know from those where aoes go, too??? Woaaah....
