Thanks for sharing your concept of creating a video trailer, and this will be relayed to the E&A team, @Yusuke Yamada. Also, I'm hoping for a new defensive building or additional levels for the existing one.

First, fix your KNOWN issues such as:
1. Alliances not getting their war loot,
2. Viper2 not hitting targets from long range but going right next to highlighted target,
3. Cracking Down on cheaters and hackers
4. Not being able to attack certain bases during missions...we just get error code when trying to attack
5. Buttons not working some of the time.
6. Real customer service, not just bots responding with predetermined responses

Lets start with these then we can talk about cool improvements that I'd love to see such as:
1. Having a centralized "store" where players can buy instant training boosts (30 min, 90 min, all day), gunships, etc.
2. The ability to gift anything (gems, training boosts, items crafted in war factory, etc.) to anyone
3. "Friendly matches" where you can attack friends accounts without medal or rss gains or losses so we can give feedback on how to better setup bases.

But start by fixing the known issues. It's not that difficult.

I just noticed the original post was written 6 1/2 YEARS ago and I haven't seen one suggestion implemented. What a freaking joke

Se hace en falta la parte naval y un mayor botin para las cuentas grandes.

Command powers, tactical nuke to be more specific, makes the screen rather shaky and can mess up unit microing. An option to disable this will be appreciated.

My idea is: Pandemonium, he uses a minigun to destroy his enemies, his super is really interesting: he fires a homing missile which you have to enter the target!
For instance - With HQ lvl 8, Pandemonium Level 1, has:
14500 HP
680 Damage
800 super damage
PS the super Makes area damage
