This game is fully playable as F2P, you don’t need to buy IAP’s however it will naturally take you longer to get decent heroes, that being said, even with decent heroes it’s still a lengthy process to level them up. This game has many grinding properties, if you want to play this game be prepared to be playing for several years before you accumulate a good depth of fully levelled up heroes and troops. It’s still fun nonetheless. There are downsides, pull ratios are low, you will mainly get season 1 heroes which are not as powerful as the newly released heroes. Power creep is prevalent in this game due to the nature of new heroes being released constantly, however as with any game of this type, you will come across stronger opponents, and you will come across weaker opponents. Some events are clearly tailored to high level players so you will not be able to complete them, but this is completely understandable. Events often have multiple tiers of difficulty for this reason.Be wary of spending money on gems etc as you will be unlikely to get what you want in the summon gates as it is random, but the pull ratios are accurate. Ascension items are rare so even with high level (5* characters) you may not be able to level them up/ ascend/ max them for a long time. This game is better played in an active clan/ alliance. The more you contribute to the alliance (titans, wars etc) the more rewards you will get which in turn will allow you progress faster. The game has a lot of content/ levels and challenges and there is plenty to do. Do not play this game thinking you will achieve greatness in a short time frame.I really enjoy this game, I buy IAP’s infrequently so I’m not fully F2P.
