Aw yiss internet fight, prepare for the wall of text.
It's like LoL without (most of) the cancer part, it is supposed to be a lot different compared to the existing mobas, as well as fixing their mechanics. It still has a rather small hero pool, so every single hero is pretty much unique,same goes for maps. Also it has no item and ingame gold system, so all the last hit bullshit is non-existent, instead every hero has talents tailored to their style, and those are tied to team levels(and exp).
Also the maps are objective-based, and the game is fast-paced, which means a 30-40min match is considered rather long, also there's no boring laning phase for the first 15mins of the game.
The only thing where hipo is half-right is that the game is a lot more team-oriented, and while individual skill is still really important, you can't carry an incompetent team like you can in other mobas. Exp is shared accross the whole team, and the matches are all about winning teamfights near objectives. This is what team games should be about imo, and not individual ppl doing their own shit all over the map.
Also, the snowballing is non-existent in a way hipo described it, while it might happen with useless retarded teammates, I haven't seen a match that isn't winnable at a given time, no matter the exp and level difference compared to the enemy. Thanks to the comeback mechanics of the game, with a coordinated team you always have a good chance to win as long as your core health is greater than 0%. And I don't see why you wouldn't have a proper team, as playing a team game with absolutely random people sounds retarded, and definitely won't yield good results.
Moreover, if you're stupid enough to go solo q and get matched with random players in hero league, luckily the game isn't lost at the picking phase, as almost all the team comps are viable (as long as you have a support/healer), but I still would recommend a team of friends or good players.
Also, only the newer heroes cost 10k gold(which is like a month of casual play), half of the most commonly used and best heroes are really cheap, and can be bought for 2k, 4k, or probably 7k.
tl;dr:
Come and play with me if you're in EU, I can also get you the newest hero which is controlled by 2 players.
