Either the fact that players here are sooooo bad or this game is full of bots still won't be enough because of how expensive everything is and as a f2p you'll be stuck at using 2 (3 most) heroes for a very long time unless you use them below average which will burden you and your team. Paying for iap isn't that great either considering how expensive everything is for how low you can get from it. There's also no casual play here (except for events) so you're bound to waste mmr and streaks.
