Ok so after having played for an entire week long these are my impressions. Game is good but i have seen players with 300k-700k power so sooner or later i'm guessing the "tactical" part of it goes away and it becomes just brute force everything, that doesn't happen overnight so it happens later i'm good with it also the game is very new so alot more content can be added with time so i have a few minor suggestions maybe that i think would be nice.

1-When we open the game we are presented with the "city" we can slide left and right between Alliance Hall - Astral Podium - The Arbor - Battle - Emporium - Elemental Sanctum. These are all obvious and well identified but we also have the Special Challenge, Daily Challenge, and right now Marnie Special event these last 3 might be sort of temporary things i guess and they are easy to find but are not so obvious, having text like the others would be nicer.

2-Also regarding the city first screen i feel like having some of the information we can find on the Player Profile button on top left being permanently displayed would be better (namely Food - Gold - Gems)

3-Battle takes us to the 5 regions maps, here without a doubt while scrolling them we should have a permanent display of Food without needing to select a battle and possibly adding a display for Marks would be nice. (either all at once or maybe the Mark corresponding the map you are seeing)

4-Furthermore regarding the maps all we see in them is the traced line with battles along the path and their Tier... More important than the Tier i think would be having the name of the battle (Tides of War - White Squall etc) marked on the map itself because when we use Astral Podium for example to Raid specific Heroes or Troops we have the name of the battle for them but then we come to the map and we have to open 1 by 1 if we want to autobattle to gather the specific thing we are looking for.

5-Dinnertime Feast and Lunch Rations daily duties these are quests for login in during two different 4 hour periods... I'm assuming here the game runs on a "global" server (America and Europe) i don't see this working at all unless thats not how the servers are working. Still even then you could easily extend to two 10 hour periods would achieve the same goal (people login in 2 times a day at least) and be more flexible.

6-Heroic Tokens. The only way i can find right now to know how many Heroic Tokens i have is clicking-holding on the reward displayed on Special Challenge... as far as I can tell there's nowhere we can see how many we have.

7-Inventory could use some more functionality like upgrading runes and tactics directly from it would be nice and having a tab for Artifacts maybe.

There's some other stuff but the post is already very long so one last thing.

The S-A-B-C-D rating system for Heroes and Troops is alright but i'm actually trying to get some concrete values for troops right now maybe Heroes and tower later i dunno. I'll work on it as i progress on my own but I could use help from more veteran players on it follow link:

Also i forgot last suggestion to the Dev team... Ingame chat is good but maybe opening up a Discord server for the game. Make it an Unofficial "official" Brave Order server requires little to no maintenance and you can probably even find a couple of volunteer players to act as mods.
