I fully agree. it would also probably promote more energy sales and gems to energy conversions if people had an easy fast way to burn through their energy with more autos. 

then convert the passes to just give out more energy daily instead of autos.

unlmited autos would be a huge QOL improvement overall IMO.

Considering that using an autoclicker is cheating and that it also "conflicts" with the raid pass offer, I'm surprised Plarium doesn't ban people who use autocklicker scripts. But at the same time, I guess they know how grindy their game is and don't want to lose players. In that regard, they technically should just add such a feature to the game, but I guess that could lead to fewer people buying raid passes, resulting in a lower revenue for Plarium (although their main income is probably coming from selling books and shards anyway). Maybe they should change the raid pass in that it gives you infinite multi-battles.

I think giving infinite multi-battle to F2P isn't really needed. These players don't have that much energy and it may also be off-putting to newer players to have infinite multi-battles. There are already plenty of people who avoid games which have auto battle mechanics to begin with, maybe it would be even worse if there was infinite multi-battle. If you think about it, it's basically pressing one button, going afk, taking a shower, eating lunch, going to sleep and return later with the hopes you got that one 0.01% RNG roll in dungeon 20. It's not like that in early game, but the longer you play this game, the more it goes in that direction. Maybe that's also why Plarium doesn't bother with banning people who use autoclickers, because it's only a marginal percentage of the players and most of them paid money in some way anyway.

So, I think the main reason against implementing infinite auto-battle (even if it was a paid feature) is that it could be off-putting for new F2P players to see such offers. Other than that, I can't really think of a good reason. And in all honesty, thinking about the high number of pop-up offers, most of the people who would be against infinite multi-battle would have uninstalled by now either way. It seems like there is no good reason not to give infinite multi-battles to spenders.
