My QoL suggestions 
- 2021.07.09 02:07 (UTC+0)
before I get started. Yes, this log in is rank 7, been playing since around first anniversary on multiple accounts. Just don't have access to my mains email, thanks to hacks.
Now, what I would love to see improved, in no specific order;
1. At every bi-monthly balance patch a recall item be given (or an option to buy for players.) this one is self explanatory imo.
2. Since we seem to be getting new heroes nearly monthly, the ability to gear/awaken/mola I feel needs to match this. Ie increase charm acquisition rates, add greater charms to content drop pools, increase catalyst drop rates (especially epic's) etc.
3. In continuation from above. show catalyst drop rate % in maps.
4. add 1.5x speed to cleared Story / Side story content on cleared maps.
5. Clean up UI clicks needed to enter tabs (like back click memory) Ie so if I click the sidestory banner I am taken directly to the side story map instead of side story interface. where I then have to click through 2 more menus to access content.
6. Add sliders to hero xp / penguin use.
7. balance the reputation rewards to actually be rewarding ie "you have accumulated 200 million gold - here's 40k gold" not trying to sound ungrateful for the rewards we do get for just literally playing, just feel this could actually be beneficial for all players. but also extend the limits of said reputation rewards. when you get late game you get F all in that regard.
8. Add sort hero menu - Speed. hard to remember which heroes are my fastest sometimes.
9. stop pigeon holing content to require, what almost feels like specific heroes. this goes hand in hand with suggestion 2. don't get me wrong, I like the latest content. just annoys me having to build specific heroes for said content, to only sit them on the bench for nearly everything else. Yes, I do understand that certain heroes can be used in all content, but I feel that having a fully geared hero just sitting on the bench for specific content is a waste of time and resources.
10. If you do continue to require certain heroes for content, in the weekly log in events that we have, remove random hero tickets and replace with RGB selectors. I've been dying to get my hands on Roana (missed her banner) would love to be able to choose which hero I get instead of my 8th Haste...
11. hero to hero gear transfer button. again self explanation.
12. AT +15 gear, give the option to choose which sub stat to roll. you can still keep you RNG but at least let us choose our disappointment for a low roll.
I'm sure more will come to me, and again these are just some suggestions I would love to see. I know most of these look like mid game ideas, but since not everyone has a mad stockpile of every currency available. feel like these benefit mid, vets and grandvets too.
