Some fairly implemented features I'd like to see

I'm sure Intelligent Systems is getting plenty of feedback about the game, but what I'd like to do here is get everyone on the same page so that the feedback they receive is more uniform. When a developer gets a bunch of different suggestions it could be hard to "Focus" on a clear direction and figure out what the players actually want (and what they can afford to give them).

What I'd like to highlight are two features I'm seeing a lot of people asking for. Those being what to do with excess SP, and the ability to re-roll a unit's stats. I recently wrote up a 1000 character letter for Intelligent Systems (not yet sent) that sums up what I think would be a fair way to implement these features:

"Once a unit has all skills unlocked, SP on that unit just piles up. I propose having the ability to convert SP into shards/crystals once a unit has unlocked all it's skills (having the unit also be level 40 could be another requirement). The shards/crystals created would be of the color of that unit and the conversion rate could be something like 1 SP = 1 shard and 5 SP = 1 crystal. Any conversion rate works, what matters is the ability to do so to give players something else to do with their maxed out units during end game.

Another feature would be the ability to "re-roll" the stats of a unit. The community has started calling these hidden stat differences a unit's Boon and Bane or IVs (individual values). It sucks to summon a rare 5 star unit and then find out they have a horrible IV distribution. The feature to "re-roll" stats could cost like 5,000 hero feathers or so and the new distribution would be random. This would again give players in the end game yet another thing to do."

My wording might be a bit weird at times due to the character limit, but I hope you all get the gist of it.

So now to address some things you all might be wondering. For starters, yes, those conversion rates for shards/crystals and cost to re-roll stats are meant to be harsh. Given the nature of freemium micro transaction mobile games, asking for handouts (that aren't meant to keep having you come back logging in everyday) often get ignored. If we want something to be added we need to make the offer enticing to the developer or else nothing will be added at all. In this case, extending the life of the game and having it stay relevant for a longer period of time by keeping in line with the natural grind.

I've heard some players want SP to be converted to hero feathers, but I don't think that would work with the nature of how hero feathers are already earned. Since SP is gained through battle, it can be viewed as excess EXP and the ability to convert SP to shards/crystals would in a sense give the player the option to transfer that excess EXP to another unit.

The 5,000 feather cost to re-roll a unit's stats is based on the 20,000 feather cost to upgrade a unit to 5 stars. Some say that is already too high, but the ability to even increase the rarity of a unit to begin with is already generous enough and something I seldom see in other "gacha" style games. So with this stat re-roll system, the player would gain the option to upgrade a unit to 5 stars or get four chances to redistribute a unit's stats to a desired way.

In the end though, like I said in the letter, I'm fine with whatever costs the developers settle on. I just want to give more purpose to my maxed out level 40 team when I bring them into battle by having them contribute to the other units I have sitting in the barracks, and be given the option of not having a -SPD Lyn... my salt is starting to show...

TL;DR Convert excess SP to shards/crystals and use hero feathers to re-roll stats. Keep it high and it'll fly!
