Arcturias has become a favorite of mine, as has Kerrigan. I'm enjoying these dueling heroes.
I have to say I'm playing less of it, going more to league and smite than HOTS atm. Probably because they are set matches every round. The random maps in quick match can get aggravating at times. Like, HOTS is good, but the matches are really short, games don't feel that coordinated, and some maps feel kinda throw away. Like, currently I love the Pirate Bay map as well as the Eternal Battle and Punisher maps mostly because its fighting for a goal at the same time. Players have to seek separate objectives or the same objective in competitive ways. The one spider level with the Widowmakers supers spiders is really similar to Pirate Bay and I like it, too. The objects aren't random, they're on a strict timer and often have both sides clammering to the same spot to fight in quick skirmishes. And Pirate Bay has players seeking each other and objectives out to take doubloons from each other and get the pirate to fire repeatedly. It's fun and makes the objective-based MOBA fun.
Some maps feel like they lack this. The Garden Terror only gets like this for a short period of time and once you've got a seed, its safe even if you die, so there's no real emphasis on fighting the other team, just getting your terror and pushing. The Dragon Knight has the problem where it creates a the 2 zones to fight in, and the rapid battle becomes more and more one-sided. Though I do kind of like it since there's a lot of strategy and on-the-fly responses you can make, like trying to deny the dragon knight by camping the statue, or hard pushing extra lanes once they get the dragon knight or are pushing the zones too hard, but it still feels like it makes things too one-sided as you try harder and fail harder and harder to get those zones.
basically my issue with HOTS is that it feels so...disorganized...Playing with randoms leads to what feels like a really messy experience compared to playing with randoms in SMITE or LOL, since those ones have pushing and lanes you can rush where being a bit disorganized isn't a total killer.
