Quality of life improvements.
1. Auto help requests - I don't like sitting there hitting a hundred tiny little plus buttons for a few minutes after every big arena grind to individually request help for a hundred champs. Just make it automatic. That would help a lot.
2. I just want to hit the help button once to help my alliance members. Help All. Bam. Simple. Please.
3. I want express arena mode for all players, not just the sigil. And to compensate the lost bonus for the sigil buyers, just sweeten the sigil deal some other small way. Take as much time off of the arena grind as possible. This should also be automatic with no loading screens and it should pick your top 3 champions over and over until you hit some quit option. Like at the end of the third fight of each set, it tells you what you want and gives a 3 second window to quit or it automatically goes onto the next set of 3 fights, where the champs are automatically chosen from the top of the player's roster. Include a "Go now" button, which I will tap just as soon as it's available to save 3 agonizing whole seconds.
