Re: Please allow us to bank 4,000 tickets.
I disagree with the idea of banking tickets. The way it currently works, makes the player play the game every day if they want to get those event cards for free. They go online and play a few matches, complete their quest and watch some ads while they at it.
Why I disagree is: If it was allowed to bank tickets, players will no longer have to login every day. They can just forget about the game for a day. Which means they won't go online, play matches, complete quest and what might be possible the important reason of all; they won't watch their ads on which the game makes money off of.
Sure, there will be people that still play it for the gems but the amount of people will be drastically lowered. Heck, there might even be people complaining that the game doesn't offer enough free gems while they aren't playing themselves, BECAUSE the game allowed them to forget and take a day off. If it wasn't for the event cards I wasn't playing the game every day and I wouldn't have gained those free gems from quests and ads which I used for Galactic Gardens packs.
The idea of earning tickets when you lose is a bad idea and will be abused. You can just concede or disconnect the first turn when you start the battle and repeat.
Increasing the tickets isn't necessary either as you can currently easily earn all four copies just by playing and if needed spend your earned gems towards boosts or flat out buying the cards. Just like a few people mentioned already.
