AFK Arena

Time limited events that force you to be active daily

You have a timmer thats for 36 hours if you dont come back them you gain nothing so you have to come back to reset that clock and be able to collect "AFK" rewars

Its not energy but you can skip a lot of waiting and get a lot of stuff by buying vip and other shit

You can allow other players to take a charecter of yours everyweek or even rent one of your premium charecters aka dimentionals

In the sense that you can pause battles but you can not save progress until a battle is complete. Higher battles require multiple wins. There are also some events with other players.

PvP is largely pay to play at the top.

Yes there's a variety of timers to procure resources over time. Sometimes you need that to proceed.

There's an optional subscription option of three sorts now and each new event has a reward bracket you can pay to gain good rewards for each free level you progress through during the event. These are also no longer invisible to f2p players.

There are skins that are rewards during events rather than using the event currency to get rewards to help upgrade. You will need to upgrade a hero far enough with copies of itself and fodder hero copies to get it to Red which allows it's emblem to upgrade. Then you'll need red to go from red plus and then white to access it's furniture then you need an extra star which requires two copies of itself for most heroes so you can upgrade it's rank. These all add new powers.

Yes you'll miss an event which won't usually have too much impact but you can. You easily miss very time limited codes for minimal or sometimes additional content. And there's always the chance of missing out on the balloon ride that appears every week or so. There's additionally the risk of losing the meta.
